I own the 2002 RSX and I absolutely fucking love it. I never test drove the WRX but I know a friend who has it and he loves it too. Tough call for sure, but I would take the sportier look that the RSX has. One thing I love about the RSX is actually the trunk space. It's a sportscar but it has tons of room in the trunk and the 200 horses makes it very sweet!
In the 2 years I've had it, not one single problem, ever. I absolutely love it
