I ran R2 Hard Case Lights in 32mm on my Trek X-Caliber mountain bike because I was using it only on the road. I liked them. When I got my road bike I tried some GP4000s but they didn’t hold up well for me on my roads and at my weight (250).
I went to Tubeless rims on my road bike and installed some Specialized Roubaix Pro tires in 32mm. It’s a very nice tire for about $45. Rolls a little better than the R2s, though honestly I couldn’t comment on noise as my hearing isn’t great. I’m now running the Roubaix Pros on two different bikes. They have a slight bit more rolling resistance than I’d like but in about 5000 miles of riding I haven’t had a single puncture that didn’t seal. I can’t comment on how the puncture resistance would be with tubes, but I’d imagine on par or slightly better than the R2s based simply on the feel of the tires while installing them.
Im not sure what to say about comfort. I run them at 80F/90R. Comfort seems about the same as any other 32mm tire I’ve tried.
