It's hard to tell. The Contour has the smoothest powerband of them all, almost making it feel slow. I have not pushed the brakes yet but I can tell the Contour would out handle the MS3 just simply based off the similar weights and the CSVT having a LOT of suspension goodies.
The Mazda just has LOADS of TQ everywhere, It's great around town and would probably out run the contour in many situations. The brakes are amazing (stock) and the car does absolutely everything you want it to down around the corner. VERY composed.
The SHO would just walk them both, maybe a little less TQ down low but the aftermarket cams just make it scream up top...all the way up to about 7200+ RPM...Although I regularly shift at 8,000 RPM's. This is all off the bottle. On the bottle....well, It's just not even a fair comparison. As far as handling...well, I autocross the car with 275/40/17 slicks up front....so no comparison again. However, the car is setup loose....the rear end will come around very fast on you if you are not prepared (On course that is). The braking is excellent. It's just some Cobra 13'' brakes with HP+ pads but the SHO's weight (2840) just makes sure that everything that already worked well on a full weight SHO, works 2 times better.
