I'm not a fan of any of the winners, so this is mostly based on how good I though they were during the series, I guess.
1. Leona Lewis - Her voice was always good
2. Matt Cardle - I know he isn't popular on here, but I felt he was talented and won in a year where they really didn't want him to win, so overcame a lot
3. Alexandra Burke - Not a fan, but she had some really good performances and won in a competitive year
4. Shayne Ward - Can't remember him that well but remember he was a good performer, and is kinf of here by default!
5. Steve Brookstein - I always felt sorry for Steve. He gets so much stick, but I felt he had worked hard as a musician and deserved a break. Can't really remember the series much now though! In some ways, be attracted the abuse because he obviously had a problem with the show so probably shouldn't have gone on it in the first place, but I have picked him for the reasons above.
6. Joe McElderry - A sweet boy but I wasn't ever wowed by him, unfortunately
7. Leon Jackson - He seemed like a lovely person but his voice wasn't my style and he probably got most of his votes for being cute (not that that's his fault)
8. Little Mix - the "chosen" act in a crap year. Relied entirely on the producer's help to win. I'm sure they will be successful but in terms of the show, I thought they were awful, contrived and completely pimped for the win.
