I watched most of the Gundam series because of how much I got into the Dynasty Warriors Gundam games, and after getting the platinum trophy for Gundam 3 on PS3 I finished watching the 22 episode Unicorn series because of how overpowered the titular Unicorn Gundam was in that game, followed closely by the God Gundam and the Knight Gundam. I didn't really like it at all, felt kinda whiny. I still like Wing because I watched it as a teen, but I'm still not a fan of the artstyle that much. So I think all in all the original is my favorite, with Amuro and Char generally keeping my attention more than most of the later characters.
