The N52, on the other hand, was responsive and had a very sweet growl plus it might have been the smoothest engine of all time.
I can definitely understand why someone would prefer either engine over the other, I'm not sure which one I like more to be honest. I think I favor the N20 just because of its surprisingly huge low end torque, the N52 below 4,000RPM feels downright slow in comparison.
