After checking out the highly rated Hankook Optimo H727's we decided to instal Toyo Versado's on my girlfriend's Honda, too early to tell after only a few weeks, but they ride nice and quiet. We bought these partly because I had Toyo Open Counntry HT's on my last Silverado which I felt were excellent (Winter directional stability was good due to the deep grooves in them, but traction was somewhat below average). Toyo has some decent rebates this spring that you may want to check out, if you go that way.
I can't comment on the Potenza's but a friend of mine has Bridgestone Duellers on his Sante Fe as does his wife on her CRV. His are lasting alright but hers were done after 60,000km(40k miles). Even though they are both Duellers, they have slightly different tread paterns on them for some reason.
I would check out the Hankook Optimo 727's as well as the Toyos. There's some other good brands out there too...
