To answer your question @Rai, I find season 2 much more unwatchable than season 9. Beverly was treated terribly by Heather and Sarah, but Grayson defended her multiple times. (It's a shame that Grayson came back in a later season and had a shitty attitude; I really liked her after her first season.) Heather was eliminated pretty early in the season, which just left Sarah to hate on Beverly by herself. In season 2, everyone was against Marcel, culminating in an actual assault. Even Elia, his one friend, turned on him. Plus, at least Sarah didn't win her season. It was awful seeing Ilan win.
Speaking of winners, Top Chef reminds me of American Idol as the past winners are kind of a mixed bag. Harold from season 1, Hung from season 3, Stephanie from season 4, Michael from season 6, Richard from the first All-Stars, Kristen from season 10, Mei from season 12, Brooke from season 14, and Joe from season 15 all seemed like solid choices when they won and they've been pretty successful. Ilan from season 2, Hosea from season 5, Kevin from season 7, Paul from season 9, Nicholas from season 11, and Jeremy (who I don't even remember) from season 13 seemed like really underwhelming winners and we haven't really seen anything from them since their wins, though I don't follow them super closely. (I didn't include Kelsey since she won pretty recently.)
