Tbh, I didn't even watch the first three seasons, so I can't comment on those. For me, I always wanted Sharon to win on season four, even though after the show finished she turned into a bit of an egomaniacal douchebag. I never liked Willam tbh, she always seemed like such an attention seeker and I never found her jokes that funny or her look that amazing. And in season five, I was always rooting for Jinx, even though again I didn't really like her after the show ended. Jade was super cute as well tho.
