Absolutely it's not even a contest. Even an upright will sound much better than an electric. I've bought one of the best electric pianos you can buy (Yamaha N1 which has the same action as a grand piano) and it still didn't compare. That's not to say the electric ones are bad but there is just much more nuance you can achieve on an acoustic.
