Which tyre company does the best job?

[D_Marshall]

I know there are a couple of threads on tyres but these only dicuss if the tyre companies have a problem because of the recent blowouts that have occured.

What i am wondering however is which tyre company does the best job for it's teams? Looking at Bridgestone, they have been quite dominant on the race wins this season but it is only with Ferrari. What about the other teams it supplies? When looking at the time sheets it is generally the two Bridgestone Ferraris at the top and then a big group of Michelin runners. Does this suggest that Bridgestone only care about Ferrari and neglect the other teams to try and give Ferrari a perfect tyre for their car? Michelin haven't had the outright success but they have been nearer the top with most of it's teams and seem to treat them on a more level playing field.

I suppose the question is if you had an F1 team which tyres would you want to use?
