RSRs are comparable to the RT615s in my opinion. They're sticky at first but they lose their grip once they get harder. I think they're lower tier tires compared to the likes of Dunlop Star Specs/IIs, RE-11s, Hankook RS3s, AD08s, and PS2s. Kicker is, those tires are going to be more expensive and harder to find for your size.

Personally, I prefer symetrical threads over assymetrical ones. Gives you the option to flip the tires when/if you get too much camber wear, so I'm partial to Dunlop, RS3 and AD08.
