Tyra Sanchez, Season 2. This one is actually close because I also didn't really think that Bebe deserved to win, but between the two I'd say Tyra is a much worse winner overall. Yes, she was never in the bottom, but she has a shitty personality, isn't really that talented or creative, and the overall talent of season 2 was lacking to begin with. The final three was pretty strong simply because of Raven and Jujubee and then Ru was just like "fuck it, let's let Tyra win".
Day 5: Queen who didn't deserve to win...
