The idea of magical girls in anime series is nothing new. Cardcaptor Sakura and Fate/kaleid liner Prisma☆Illya both explore that territory. They both involve young girls who uses and collects cards in battle against supernatural forces. Cardcaptor Sakura's cards has a deeper meaning though but both series maintains the magical girl trope well.
The main female characters are inexperienced at first but later gets more experience with their partner. They're also shown to be kind and cheerful with everyone at school. Both series also has action along with comedy and drama. There's also a sense of competition among collecting the cards.
Both are about magical girls that use cards to fight with. Cardcaptor Sakura stays true to the essence of a magical girl story while Fate/kaleid is more of a modern spoof of the magical girl style of anime by placing the characters of Fate/stay night in a hilarious setting.
Both entail card capturing and fighting with the cards in order for this to be done. But Prism Illya is definitely a more serious version of Card Captor Sakura with badass fighting sequences and more!!! Main difference is that Prism Illya could be classified as more dark (dark mahou shoujo) as we see the struggles that Illya has to go through by becoming a magical girl and all the doubts and life threatening situations, while Card Captor Sakura is more fluffy and cute, without much violence or blood.
Everything starts off cute and girly, then an accident happens where the main character discovers that she's a special person related to supernatural and non-human events, but makes new friends and starts to live their new lives as normal, and then the dark plot twist happens
Taking place in alternate universes, both series features a strong female cast with a small colorful cast of characters. There is magic/power to behold and discovery as the story progresses. The main female protagonists trains to master special powers after discovering she has a special gift after one day. Although they both have a story, at times, scenarios will give off a slice of life feeling. But despite this, there is a decent amount of material covered from their adapted manga works. If you're looking for a series with cute girls and energy, give these two a try.
Both series are Type-Moon related franchise so expect some of the same characters to pop up here and there. But more importantly, both series are VERY funny for their humor. In fact, both series are portrayed as parodies with no direct/serious plot to the whole.
There is a lot of funny dialogues as well as comedy going on. There is also the school life background where even more comedy ensures.
Verdict: watch for the humor and entertainment rather than taking either series seriously.
Carnival Phantasm and Fate/kaleid are part of the Fate franchise, but on a alternate story. Unlike it's parent franchise, they both have a lighthearted, comedy atmosphere, where characters interact with funny dialogues and segments. You will see most of the returning characters, who are going to be a either a running gag, or in a cute appearance.
Carnival Phantasm is somewhat a variety genre where they show gags and comedy segments, but no story. Fate/kalied follows Illya who is a normal school girl until she was contracted as a magical girl.
Both Madoka and Fate/kaleid are rather dark magical girl anime that deconstruct the genre.The main character has to face the dangers of actually being a magical girl. Several of the characters between them are also similar.
At first, both anime seem like lighthearted magical girl shows. However, further into each series you can see a deeper, darker storyline develop. Madoka Magica is the darker of the two series, while Fate/kaleid is more comedic.
Both are a dark twist on the concept of magical girls.
Although Fate/Kaleid has much better animated fight scenes than Madoka, along with a better looking animation style, it's story doesn't meet the quality of Madoka's.
Plus, in Madoka, the girls are forced to fight witches or else, and in Fate/Kaleid, she isn't forced to fight, she just chooses to.
And Fate/Kaleid is bloodier.
At first it looks like it's cute girls doing cute things, but its quite far from that.Both anime have slight hints of yuri and have a large amount of girls. The main lolis are voiced by the same VA. Cards are the source of power. They have to fight monsters with the power of cards. Both have a rather dark atmosphere.
Both shows are mahou shoujo anime in which young magical girls get their power from cards. The magical girls also travel to alternate dimensions to fight enemy monsters. Also, the protagonists and both shows are very cheery, always trying to lift the spirits of those around them. Neither show is directed towards an audience of little girls.
Both are spin-offs from a Visual Novel (Nanoha - Triangle Heart and Illya-Fate) taking a secondary character and making her a Mahou Shoujo. While Nanoha as a franchise is much better still Prisma has many Nanoha references .
Illya and Nanoha, the main characters of both series are "normal" schoolgirls who become magic girls accidentally. During the task of collecting something, Illya and Nanoha meet their rivals, Miyu and Fate. They gradually understand with each other by battling and become good friends finally.
Both series seem to be intended for little girls, but they are actually lolicons' and yuri lovers' favourite. Action scenes are also great.
The first season of Nanoha (but also the rest of the series and movies) are definitely similar to Prisma☆Illya as they show a darker side of the mahou shoujo gender with intense fighting sequences and actual life threatening situations, its made clear that just because because you are a magical girl you cannot use the same lovu-lovu supaaar kawaiii raindow attack to defeat all your opponents, training, strategy and experience are a must. Showing the struggles doubts of the main heroine is also included in the packet.
What stroke me as the most similar element is the fact that the magical devices have a consciousness of their own and they can actually talk and communicate with their master. Apart from that:
Illya=Nanoha (MC that is always cheerful and finds the way to move forward through various events/discovering their potential little by little)
Miyu=Fate (the troubled and at first hostile/mysterious/rival character with the unknown past who then becomes best friends with the MC) read more
Little girls risking their lives fighting in Alternate Realities while being monitored by some mysterious organization.
Both anime seem to fall into the Action, Fantasy, and Magic genres. Have a 'normal girl' MC who is forcibly thrown into an alternate dimension/reality. Another MC girl who is already adapted to the situation. And a secret organization trying to get them to accomplish some goal. The two MC quickly form a strong bond and their are slight hints of Yuri. In a time of crisis, the 'normal girl' MC may awaken hidden powers.
The focus seems to be on the bond between the two MC and the unique and secret alternate reality which they share. There also seems to be a focus on the relatively unchanged daily lives of the MC, but it's too early to tell for Flip Flap.
Moe, moe, moe. Both anime are filled to the brim with moe and battle girls with surprisingly good animation and art. Girls slap on gear to make themselves full battle-ready and fight enemies that threaten the peace of their worlds. There is also a surprising lack of male characters, though more so in Kantai Collection.
Magical girls/boys are forced to find objects (cards in Fate/Kaleid and dance stones in Brave Beats) by allies they meet. Once a specific card/dance stone is collected, the characters can use that power in battle. Brave Beats puts a dance twist on the Mahou shoujo genre and is geared towards kids, while Fate/Kaleid is for an older audience.
Do you like lolis? I like lolis? The adjective/noun known as 'Loli' can be used to define these two anime. Too bad that's all they have in common. The Fate/Kaleid series AT FIRST appears to be a rip off of the critically acclaimed Fate Series and the horror anime known as Madoka Magica. After watching two or three more episodes your realize that you were damn right about the series. On the other hand, Toradora is a romance anime that intimately follows the developing relationship between two unexpected lovers, without all the generic shticks that are seen in the previous anime mentioned. TL;DR Why the hell did you watch Fate/Kalied when you could've watched Toradora. read more
-A character who initially don't want to do their job
-Monster of the week trope
-The characters work on team, one of the teammates seems to hate the protagonist at the first time
-The hardships of fighting the enemies
What if Illya was raped by tentacles? Both are semi-parody of magical girl anime, protagonist is forced to wear revealing clothes and go through embarrassment. Illya and Elena share the same flustered personality, and same kind of humor; Elena makes funny comments when she's raped instead of just saying "Oh! No! feels good!".
-Both are light-hearted (when compared to their parent stories) magical girl anime
-Both main characters are 10 year old girls with a magical companion
-Nanoha Vivid has more sci-fi elements while Prisma Illya is more supernatural

The concept of magical girls isn't new to the anime industry. As such, Shugo Chara and Fate/Kaleid brings that idea once again in these two series.
Amu Hinamori and Illya's lives are both changed forever after one faithful day when they meet a supernatural being. They form a sort of contract/deal and now must collect/help with certain tasks. Along the way, they also form alliances with other characters while also struggling with adversaries. Through experience though, they become more skilled and in mastery of their new-found abilities.
There is romance in both series although less so in Fate/Kaleid. The tone of both series is also lighthearted so expect recurring jokes and humor.
