Vettel will almost certainly have the faster car. If they fight it out it might be clean but it wouldn't be "fair". That's f1; every year we argue about whether the champion "deserves it", when often they only have to be better than 1 other driver half the time.
The Ferrari is not as bad as people suggest. It might not have outright pace, but if Redbull knew how to make an alternator the championship would be over already. Both the challengers' teammates have made the car look bad at times. With RBR we say car good, Webber bad, but for some reason it's the other way round with Massa and Ferrari. We like to think Alonso is getting 101% from the Ferrari because it's a better underdog story.
People say we need Vettel to move to another team to prove he's a "great", but why? He should stay there and win every year, this is f1. If you want to compare drivers you need them all to go to one make formulae, or one team in f1 fielding 24 cars. Oh well, good season on the whole.
