I just got out of an RA into an M2 base. The cars are not in the same league. M2 is twice the car, easy.
One thing I will say, the RA has better steering and better clutch/shift feel than the M2. RA's steering is hyraulic and much more communicative. The clutch is heavier and shorter than the M2 and the throws are shorter.
Power? No comparison.
Handling? They both have insane grip..... its really a matter of understeer vs oversteer. Because i'm a relatively novice driver, for the time being, I could definitely drive the RA faster and more confidently than the M2 in anything but a straight line.
here's my favorite review of the Type RA from my favorite reviewer, SavageGeese, he absolutely nails it:
