Indy 500's are merely acceptable in the wet. Good hydroplaning resistance (10+mm of tread depth helps) but they just don't stick on a damp road. You'll be all over the place. When they wear, though, they're horribly sketchy. Fun, but sketchy.
Not sure about the GMax RS, it's a new-ish tire.
I had Kumho Ecsta PS-31's for a while and they were really good in the wet even when worn.
PS4's are where it's at though. They're worth their weight in gold, just about.
