It's almost too hard to choose. The CSL is viscous, the original M3 is familiar and wonderful, the GTS is borderline pornography and the 1M screams like the fantastic inline 6 we all love. Hard choice.
My vote goes to the CSL. I've heard it in person and it is spine-tingling. As for a V8 sound, who doesn't love the sound of a grumbly V8? The M3 and M3 GTS sound great, but I think Mercedes-Benz' 6.2 AMG sounds much better. Just personal taste I suppose.
