I love Gundam! I really only like the series in the Universal Century though: 0079, 08th MS Team, 0080:War in the Pocket, 0083: Stardust Memory, Zeta, Char's Counter Attack.
F91 isn't too bad and I haven't seen Victory but ZZ completely sucked.
I also like Wing and what I've seen of Turn A, but I'm not really into Seed
The MS-18 Kampfer is the greatest suit ever!
