that's a pretty steep question you got there, hehehe.

Probably it depends on the genre, I'd say Clannad or Sakurasou no Pet Kanojo

Damn I've still not seen Clannad. Keep putting it off.

Samurai Champloo, mainly because of the music

Evangelion if youre into dark and psychological themes

I like one not so popular but really exciting anime - One Out. It's about baseball but the main hero is very clever and even if he hasn't vitality or power like others he can outwit while playing and even in many other levels higher.

it might be about science and time

No Game No Life (Second season when!?)
Sunday without God (Not a religious anime)
Youjo Senki (Animation is weird, but loved it)
Fate/Stay Night Unlimited Blade Works (Because Rin is best girl.... Also because Shiro isn't a weakling in need of protection in this one)

[Abordage]

Death Note. It's just out of competition.

Also liked Hellsing. It's not as good as Death Note, but it's nice.
