I currently own both cars.
Type R is overall a much more performance oriented car, it doesnt suffer from torque steer as badly. The suspension feels more solid. The engine is smooth as butter and its ultra consistent and predictable. The tranmission is bar none the best I have ever shifted. The brakes are comparable on both cars. They both have terrific steering. The type R has independent double wishbone suspension while the mazda is strut based. This makes a difference in handling and the advantage is with the R. For day to day daily driving, the mazda takes the cake, its quiet, has A/C, isnt a theft magnent, and doesnt make every ricer on the road follow you. At the track and HPDE's the R will shine and show its racing heritage. The mazda is a perfect daily driver if you've owned an R and want something a bit more civilized. The stereo in the mazda is AMAZING! i dont even turn on the POS stereo in my R. Then again, everything in the R is in the name of weight savings. Also, the R has proven to be about 100x more reliable than my mazda. Ive never taken my R in for anything, absolutely nothing, and I beat the s*** out of it for 30k miles.
