Yeah. Mainly the same thing for me. Honestly, even if you're in a standard AWD nobody is going to be leaving the stoplight with you unless their badge says Model S.
My only pause is handling. I'm not sure how much better the P with the Performance Upgrade Package handles than the standard AWD. The one we drove yesterday was on rails. The handling of the Model 3 puts me in mind of my old e46 and e90 3 Series Bimmers, back before the 3 Series became a sportier Camry. But I seem to remember pretty much the same thing with the RWD I drove awhile back. My main nit is that I wish Tesla had standard AWD models to test drive, so I could compare the handling. I suppose at the end of the day it doesn't matter much, since even if I were to buy the P I wouldn't buy the Performance Upgrade Package, and I plan on lowering my AWD anyway.
