Try Kyousougiga! Love it to bits! 

I think those two are the best in the genre with a strong female lead. People usually recommend Ouran High School Club but I don't really like it.

The ones I find similar but not as engaging.
Sakurasou no Pet na Kanojo
Toradora!

suzumiya haruhi?
lol

Well, I can recommend to you stuff, but it depends on how you can tahan the stuff I give you.

In the 70's-80's, you can search for stuff like Aim for the Ace, Glass no Kamen, Dear Brother and the stuff like that for strong women;
Let me tell you, though it may be old, there's a reputation for shoujo back in the day to be cruel and dramatic, and it still is.

In the 90's, you could get into stuff like Sailor Moon, Gunbuster and Utena, where things started to diversify.

In the 2000's, well, there are more choices. The GitS series is a good place to go for the awesomeness that is the Major herself (which you could follow into Seirei no Moribito). Then, there are things like Diebuster where there is a good chemistry between the women main characters.

I've not completed my mind in the 2010's yet, so my apologies for not being able to remember every kind of series I've seen. Unless you are able to watch through the 2010's Lupin tv series

Also, watching Ghibli movies is often good to find strong girl leads.

...Unless you want me to say the obvious answers like Ouran Host Club, Haruhi and such. Heck, I can even call Queen's Blade and/or Ikkitousen as recommendations, since you have a VERY LARGE hole for me to toss recommendations.

Have fun~~

need some recommendation. i need comedy anime that have triangle love story (or 4 angle, 5 angle i dont mind). and then at the last, MC choose the girl/boy that he/she want.example like kimikiss, true tear, kimi ni todoke, toradora....  any idea?

If i liked K-on

what should i watch?

how about this new summer anime? any good one?

what is gate. the one i watch is dragon ball, gatchaman, durarara, gangsta, ranpo kittan and ushio to tora.
ushio to tora, gangsta and ranpo kittan seems good enough for first episode.
i already download god eater and prison school but havent watch it yet.

Jst finish ep1. Look good.

Prison School Uncensored

New season aside from sequels are kinda a let down. Let me know if there is actually anything good for original animal or adaptations that you like.
