Funny you should ask. The tire I replaced the Avid's with were the Gen HP's. They were running a $50 Visa card promotion last summer, so they were a good deal.
They currently have over 20k on them and the last time I saw them, they seemed to be wearing well. I'll know more this weekend when I get to see them again on daughter's car. I do know they have good hydroplaning resistance as I drove them in a heavy rain storm.
That said, some say they are not good in snow and ice, not a consideration in my area. Also, some question the treadwear, something I haven't noticed yet.
