You can use MS Basic Soundfonts, Musesounds or Berlin Orchestral Piano, it doesn't matter. The only thing that matters is that you apply a reverb or delay effect to the piano track. You can do that in Musescore by downloading from MuseHub Reverb and Delay effects which were originally created for Audacity. Of course, Musesounds tracks already have an applied automatic reverb so you shouldn't have to apply another reverb to it. But another thing that the Musesounds Piano might lack is the ability to nuance the dynamics. Usually you should be able to bring out specific notes you want to bring out in high relief above other notes in the same hand on a piano, by going into the properties tab of a note and increasing its velocity. But that doesn't work with Musesounds pianos, only MS Basic Soundfonts (and that is how I prefer to do it). Using MS Basic Soundfonts it then becomes necessary to apply the audacity reverb effects to make it sound better (the piano sounds by themselves aren't that different from each other I think, but they can be really made to shine with proper application of reverb, panning, delay, and bringing out the most important notes through velocity values).
