For me, some very great animes:

FullMetal Alchemist Season 1 (Too short)
FullMetal Alchemist Season 2 - Brotherhood - I'm loving it!!!!
Clannad & Clannad After Story - Must watch!!
Eyeshield 21
Ayakashi Ayashi
Kekkaishi
One Piece
Jigoku Shoujo

K-On - very enjoyable!
Nodame Cantabile
Fruitbaskets
Ouran High School Host Club.

I lost interest in Naruto and Bleach because of the fillers. I hate those. So I only read their mangas.
