Nice just to appreciate all 3 really, before they're extinct and replaced by milk floats with a face like a Duck-Billed Platypus (I'm looking at you Tesla).
I like that the m3 has a 2wd mode but I like even more that c63 has that v8 and crazy personality. I'd pick it over the other two and yes I'm very biased because i owned one and thought it was the craziest car and I used to drive it hard and it never missed a beat
