I'm on my third set of tyres.
First were stock Bridgestones which were fine and grippy in all conditions, but poor on road noise.
Then I got a set of Goodyear Asy 3's which were better grip and slightly better on the noise front.
A couple of months ago I stumped-up the extra to try a set of Michelin Pilot Sport 4 S 245/35 R19 Y (93) at £189.85 per tyre from Blackcircles.
I'm not disappointed! I'd say that they have slightly better grip than the Asy 3's (not much in it).
Not only are the Michelins quieter on the road (the Euro specs suggested they would be slightly noisier than the Goodyears) but from the moment I got them it felt like the ride improved markedly - it was like I'd got new suspension in with the deal!
They are more expensive, but the advertising suggests that I might get up to 5000 extra miles out of the set over other tyres. That remains to be seen, but whatever happens these will be my next set of tyres.
