Hey, to be honest I don't know if I'm a good judge, but I'll try my best. Ride quality is great, I did not notice a difference between the stock Michelins and these. The same goes for road noise. I would not call these tires noisy at all.
In terms of steering and handling, I did notice that the steering wheel became "heavier" after putting these on. I'm guessing my 19s are similar weight-wise to the stock 17s, so I'm attributing the "weight" to the extra grip. And grip there is, I feel very confident whenever I'm on those 360 degree onramps, for example.
I've never had a summer-only performance tire so I can't compare with those, but in my experience these are the most grippiest tires I've ever had.
they are definitely worth it for the money. There is a noticeable improvement over the OEM tires. More grip. They were quiet at first but now, there is road noise after 5 months of wear. But I still like them.
