Personally I would get the R because ONE it is a limited edition and there aren't a lot of them around. They make for a good conversation piece even with those who aren't into the import scene.

For me there was no question. I went looking specifically for an R. Yes I know a guy who ran 12.8 with his 94 GSR (moderate Mods)
A fast car is fine but If that's all I wanted I would just mod my Civic to hell and call it a day. If you have to ask then maybe a GSR is better for ya. Not to say that a GSR isn't good... It's a Honda and that's what mainly counts
Buy that GSR, it's cheaper on insurance and can be modded to be faster than a R is that's what floats your boat.
I do miss my cheap insurance rates and I miss my Sun roof on occasion but I think I'm finally getting over that. I love the Brakes
Stock 178 Hp to the wheels is very noticable over the GSR. I'm not big into leather so I wouldn't miss that, but as for the seats... the R seats seem to sit lower and give you a better driving position than the GSR seats
I drove my R 6 hours to North Carolina and back and although I missed the Cruise control at first (my First weekend having the car) I got use to it. The noise wasn't a problem cause I was driving a 5th gen Civic for the last 5 years and it is louder than my R.
