Apart from those who will only fit 'premium' tyres regardless, most of us can't really vote, I suspect, because circumstances vary so much. I wouldn't argue against the fact that, by and large, more expensive tyres are more likely to perform better than cheaper tyres , but both test results and review websites suggest that this is not always the case.
Personally, my greatest priority is wet performance, but it is not my sole priority by a long chalk. If I had a C63 I used only for driving like a lunatic in summer, which I never took out in the rain, wet performance would not be first.
