I don't think it's fair to compare tires that mounted on different cars. So here are my comparison, based on my experience.
Start out with excellent, very good, pretty good, fairly good, good and bad)
BMW 3 series with:
Michelin MXX3
Good dry, a lot of warning, bad on wet.
Pirelli P700Z
Good dry, very bad on wet.
Pirelli P Zero
Very good on dry, pretty good on wet.
Dunlop Sp8000
Fairly good on dry, pretty good on wet.
Bridgestone SO2
Very good on dry, pretty good on wet.
Dunlop SP9000
Pretty good on dy, pretty good on wet.
On an NSX (92)
Yokohama A022
Very good on dry, fairly good on wet.
Dunlop SP8000
Good on dry, fairly good on wet.
Nitto NT 555
Good on dry, hasn't driven in wet yet.
I tracked this tires about 7 events. With very good results. I don't think they are as good as the A022, but for the price, they're really a bargain and it last long too.
For the records, I was faster (with the NT555) thru the turns then a fully modified 300ZX and Porsche 911 (930) with hoosier on them today at Thunderhill.
