Hard to say. I like all SHAFT anime i watched so far. Like Wile "I'm more of a Shinbou fan" (all his anime from Pani Poni Dash! was great). For me, best anime from Shaft B.S (Before Shinbou) was REC. Summary: No vote from me at this moment.
"In 2009, in a survey asking its respondents "which manga do you think is the most interesting?" in a pool of 6000, Kuso Miso Technique came at 11th, beating popular manga such as Gintama and Detective Conan." Wiki
First, is true, second, well it was actually pretty fun, but ef is clearly The greatest I've seen from SHAFT. (And Natsu no Arashi was pretty fun in the same way too, although it was pretty mindfuck in the end : D)
Although now when we're half-way into the summer season, I'll say ef is still The best, and Bakemonogatari is close behind, they're really great, both of them : D
It's really unfair to be made to choose between the SHAFT anime. While Zetsubou is like a elegant rapier, watching Pani Poni Dash is like being whacked repeatedly with a giant Hammer until your brain is all mush. Then there is the great Bakemonogatari. Ef is the greatest visual novel adaption. I loved REC and right now I can't think of another romance anime that captivated me like this. Damn I even think This Ugly Yet Beautiful World is nice because it was one of the first anime I've ever watched and I still sometimes think about it.
Now I think that this thread I made is very pointless cause it lacks bakemonogatari, vampire bund and arakawa under the bridge plus more upcoming animes, or better: there are always newer animes that can surpass the older ones, obviously. I mean since Senjougahara Fascination there are even more people knowing about SHAFT.
Wile said: I wouldn't call all those "produced" by SHAFT. Sometimes they just did drawings for other studios when they had no work of their own.
Yeah right. Some are joint production with Gainax for instance.
Deep in my heart Pani Poni Dash ! has a very special place: It is one of the few anime that totally destroyed my perception of art, I am not kidding ! The way Shaft combines Otaku jokes, catchy music and nice school-girls was something completly new for me :)
I also like the way they show Mesousa's anxiety. I mean, you don't see a depressed rabbit every day XD And Becky is too cute for this world :)
I love Sayonara Zetsubou Sensei to death. I have never been very fond of japanese comedies - they just don´t seem funny to me (but then again, people say Czechs have very specific sense of humour). I was pretty skeptical when I heard about it, but when I watched first episode, I loved it from unexpectedly awesome opening to very end.
