My previous cars (ED30 and Roc R) had factory fits of Conti's SC's and Dunlop SportMaxx respectively.
On the Ed30, I found that when I went to Michelin PS2's the car was more stable, quieter, and ESP less prone to trigger. The Dunlop's on the Roc were good, wore well, and gave good grip.
My current car has PS2's and I will be replacing them when required with PS3's. I have tried Goodyear F1's on my MK4 Golf, which was about 5 years ago, and I didn't rate them. Very skittish, on anything other than super smooth tarmac. I removed them and sold them on, and went back to Michelins.
Just my experiences, all down to personal taste, but I will always buy top quality tyres, and never skimp, only thing keeping you on the road. Michelins all the way for me.
