Yes, me do. A lot, actually. I can go for straight-up genre (Fruits Basket, my current favorite, is pure shoujo romance) or combined genre (Negima, my other top candidate, has action and romantic comedy elements).
The other top spot holders are Ai Yori Aoshi (seinen romance), Hayate the Combat Butler (shounen parody, with some straight action/romance elements), and <url=http://www.escapistmagazine.com/forums/read/326.145022>Lunar Legend Tsukihime (action/horror adaptation of <url=http://www.escapistmagazine.com/forums/read/326.128851>my favorite game).
Others...Full Metal Alchemist, Bleach, Naruto, Ouran High School Host Club, Kashimashi, One Piece, Gunsmith Cats, Chibi Vampire, Gals, School Rumble, He Is My Master, Love Hina, Chobits, Absolute Boyfriend, Kodomo no Jikan, Azumanga Daioh, and Doujin Work. Considering a couple more.
