Both revolve around a group of boys starting up a sports club together. They have similar characters, lots of cringeworthy yet hilarious moments and if you enjoyed one, you'll probably enjoy the other.
Cheer Danshi contains a lot of the same inspiring vibes that Haikyuu is wrapped around when it comes to not giving up for the sake of a long distant goal in sports. They also focus on male friends developing a set of teamwork skills together.
Cheer Danshi!! is still so incredibly new (as of 7/5/16), but there already seem to be some similarities between the two. Both are sports anime, both feature two main male characters and their friendship, both (this is inference in Cheer's case) have a large amount of focused secondary characters, both have two "!!" after the name...
Cheer Danshi is a Cheerleading sport anime about a bunch of hard working guys trying to make a Mancheerleading Squad. It's sorta inspiring...
Different from "Yuri on Ice" when it comes to sport and relationship, and yes not as enchanting but!! I kept watching it Because it reminded me of "Yuri on ice". It really gived me a very close vibe! The anime is awesome and has a cool bunch of heartwarming characters. I really think you will like it either way! it's worth watching <3 <3
Both have a similar feeling of a group of cheerful guys trying to accomplish things. One is about a musical and another about cheerleading, but they're both very light-hearted with passionate characters.
Even though both are incredibly new so far (12/7/16) they both have a protagonist that hasn't experienced the sport yet and a companion that is either very experienced or ready to drag them along for the ride.
Both have boys with similar aesthetic forming a group and the dynamics behind that. Them having to work together to produce stage results for a crowd where they have to look good. I feel like the art and pacing are similar.
