-one is about making anime. other is about seiyuus
-both show the dark side of industry. girlish number delves a bit deeper
-both teach you how hard making anime is and how much hard work is put in
-both have a varied and lively cast, many of them being relatable
-both seem cutesy at first but are much more than that
-both are about work
Really recommend one if you liked the other. It would be 100% worth it. if not anything, you will at least be able to appreciate the people who work behind the scenes of this medium--anime.
Both animes are about anime. Shirobako is mostly about the creation of anime itself, animating, voice acting, and the producing of said anime. Girlish number is about anime but lends a little more towards the voice actor side with a focus on the seiyuu/idol experience of promoting the anime they star in.
-both are about seiyuus and their hard daily life
-while sore ga seiyuu takes a bit lighthearted approach, girlish numbers takes a more cruel and darker one (darker as in the essence, not the tone)
-nonetheless, both are very fun to watch
-the cast is fun and quirky. relatable characters in both
-both are about working society members
Both shows focus on three girls who get work together as seiyuu and end up forming an idol unit together. If you're interested in the seiyuu business, both shows will give you a little insight along with some humor.
Both series revolve around girls who want and try to succeed in the seiyuu business. If you are interested in the voice actresses' work and want to see the anime industry from a different perspective, you can give both of them a try!
Both series deal with the main female character who wants to succeed in the seiyuu business. Whereas Rec is a mix of romance, comedy and slice-of-life, Gi(a)rlish is more realistic and somewhat straight out sarcastic view of the seiyuu community.
Rec and Girlish, share one caracteristic, the seiyu (Voice actor) industry sucks, in Girlish number this aspect it´s more notable, but Rec goes for the romance side, and the industry makes the romance even more interesting.
Both are created by the same author so they have clear similarities. They both have witty characters and almost always have something satirical to say about anime, life, culture, relationships, exc. Both draw their roots from light novels so the dialogue is very dense, and have lot of meaning to them that one cannot will miss if they gloss over it.
Both are by the same light novel author, Watari Watanabe, and put darker and realistic spins on the teenage romcom genre and the anime industry respectively. Hikki and Chitose both share a fair few character traits, and a brother-sister-like relationship are in both.
Basically same concept: girls that starts working for anime/game industry, and so they have to face the problem of every day like character designer Aoba/ seiyuu Chitose.
Both plots are funny with little drama parts.
Definitely better cast for New Game! but Chitose woths 1mld of Aoba
Occasionally sentimental comedies revolving around anime, manga, and light novels as a profession. Many aspects of the industry are explored thoroughly, such as "generic" light novels and their adaptations still being born from a place of passion for the medium, and what it takes to go from being a consumer to a creator.
Both are satirical, cynical, and make social commentary about the state of the industry (the idol industry, and the anime industry.)
Both show a view of the idol or animation world as not all 'sunshine and roses'. Which is a unique perspective, in what is a usually escapist medium.
Both seem to be light-hearted cute girl shows at first glance, but not is all as it seems...
Girlish Number seems lighter than WUG so far, but who knows...
Main characters of those series are both professionals in their respective fields.
Sakurano Tazusa from "Ginban Kaleidoscope" is a figure skater that has a talent but also a bit twisted personality.
Karasuma Chitose from "Gi(a)rlish Number" is an aspiring seiyū that also has some talent but her personality is not what most people would call "typical".
Both are comedies with really good gags and internal (sometimes spoken out loud) commentary.
This two anime kind of similar. Both slice of life anime about a group of girls. One tells the story about a voice actor and the other about high school mangaka artist. Both animation really lovely and cute also colorful, really fun to watch. If you enjoy one of this anime I bet you will enjoy the other one.
