NT01s - far superior dry grip. Work well in the rain as long as you can see the horizontal tread. Dangerous in standing water. Can handle the heat better. Need to get heat in them.
PSS - I don't think they are any better in the rain on the track than the NT01s, can go through puddles. Might last a little longer but are more prone to chunking.
If you're OK with switching tires, go NT01s. If not, I'd go with the PSS.
