Sebastian Vettel - Better, seems to prove his doubters wrong, a lot more consistent, no DNF's lowest finish is 4th.
Mark Webber - Worse, no wins in a car that's very capable of winning, forget wins, he's only achieved 2nd place twice in that car!
Lewis Hamilton - Worse, getting beat by Button, in too many incidents, 1 podium in the last 9 races in a car that's quite close if not better than the Red Bull in race pace.
Jenson Button - Slightly better, his drive in Monaco was probably his best drive in the dry this year, finishing ahead of his team-mate.
Fernando Alonso - Same, maybe slightly better since he's made less mistakes, hasn't claimed races are manipulated either.
Felipe Massa - Worse, highest finish is only 5th, his 2010 season was better, mainly due to his first half of the season.
Michael Schumacher - Better, faster than Rosberg on race pace, has improved quite a bit from Spain onwards.
Nico Rosberg - Worse, off the radar in many races, not as consistent as last year, sometimes find him lurking in 13th-18th in a few races.
Vitaly Petrov - Better, more consistently in the points, less rookie mistakes, kept up with a very experienced driver, no longer a pay driver in my view.
Rubens Barrichello - Worse, getting matched by Maldonado who was nowhere in the first few races, and hasn't reached Q3 once this year unlike his inexperienced team-mate who has got into Q3 a fair few times
Adrian Sutil - Worse, I don't whether he's worse or not, only way to compare him is to his team-mate, and his team-mate this year seems to be keeping up with him more than his last year's one.
Kamui Kobayashi - Same, would have put him in the "better" category, consistently in the points in the first half of the season, second half quite the opposite, so I think it balances out his season.
Sébastien "Moose" Buemi - Better, he can only get better as he is the Moose, a driver who is getting outshone by his team-mate in the points standing but that doesn't tell the whole story as he is getting punished for being faster than his team-mate in qualifying.
Jaime Alguersuari - Better, he is better than last year, but most of his points have been from being the slowest out of the midfield cars, therefore has a bigger advantage those around him, great qualifying from him in Spa though.
Heikki Kovalainen - Worse, he may be getting the glory in qualifying, during the race he is getting outperformed by his team-mate.
Jarno Trulli - Better, the qualifying master is getting beat in qualifying, but unusually, he is putting in better performances during the race and has got Lotus's crucial highest finish twice, which just keeps them above HRT.
Timo Glock - Same, not seen much of him this year, and is hard to compare since he has a new team-mate, the Virgin car seems worse than last year compared to the Lotus, there's talk about his motivation not being there, can't say he's doing a worse job as he is beating his team-mate.
