Drivability is subjective, and its drivability is based on the tune with how well your tuner can smith everything out. Before I went centri I had a a big NA cam. Drove on an M6, and it was smooth as butter, even in 6th gear at low RPMs, it was fine. Also it really depends on where you're going to be driving around. Not like you're going to be in high RPMs a lot. I'd take more power in the mid range.
