P-Zero Nero is a better tire but its also $30 more per tire.
I went with Conti Extremes, no snow here but the tread rating was desirable and the price was right. Reading the Tire-Racks ratings said these were rated right behind the Nero's as the 2nd best tire in the group of 20 listed as All-Season high performance.
Been on my car for 13-months and they wear well and handle pretty damn good too.
