-Bourdais is the one that ticks the box "experienced", 'cause at 28 he does have substantial racing experience, even if his running in F1 cars have been limited to a handful of tests, three relatively recently for STR.
-Vettel ticks the box "promising newcomer" and he's held in high regard by BMW's Mario Theissen, and he's not one to sling the superlatives around too loosely. (Obviously Berger rates Vettel too.)
Vettel is as we all know, in the car already, so it will be very interesting to see how he'll match up to Liuzzi given more time, but he wasn't far behind in Hungary - basically matching him I think, in the race.
Bourdais was said to be as quick as Liuzzi when he did one of his test-runs (I wonder if it was at the first one already...?), so we have a vague sign saying that Vettel and Bourdais' potential is similar.
(Then again perhaps they said he was matching their regular drivers' times just to undermine Speed/Liuzzi? well, well, let's stay clear of that discussion in this thread, OK?)
But who do you think is the quicker of the two? I'm thinking Bourdais. I think he'll prove quicker and better overall than Vettel. His work-ethic is also praised a lot, so he should be able to progress even further with his crew of engineers, and perhaps also be the one to lead the team.
Anyway, a very interesting driver pairing for STR next year, and one that should be very good.
I'm looking forward to it!
