It's subjective, so you have to go with your gut. My gut is right on the money on this one.
Why do wise men doubt themselves so much, when fools are ever-confident
That sounds like something i would start doing Galahad, only to realise half way through it was an impossible task. Although to be fair, comparing drivers to their teammates is probably the only way to quantify a drivers quality. We know Alonso's>Massa, Kubica's>Petrov, Sutil's>Liuzzi, etc.
Hamilton > Kovalainen > Trulli > Alonso = Hamilton.

Precisely. Though you can argue whether Trulli in 2010 is the same as Trulli in 2004 was. But even then it's a fool's errand. Different cars suit some drivers better than others. Look at Patrese vs. Mansell at the start of 1991, compared to 1992.
The only thing with that is if Bruno Senna was that good then he wouldn't have been with Hispania....
