Of your choices listed I like the RS-4 and Super Sport PS4 the best. Both great all around summer tire that can take abuse. I have used the Sumis and they were just ok.
Bridgestone S-04 were another decent street tire that was quiet and comfy with decent grip, low cost. It was not suitable for track use though.
