by technical it means like ho fast your octaves, thirds etc... are and finger independence and all that. by musical it means how you express the music.
So, then, you are saying that the world of music is divided into those who have the means to express something, but nothing to say, and those who have something to say and no means by which to express it, and of course all shades in between.
It seems difficult to judge for oneself whether we have more technique than musical thoughts. What is more easily recognized, however, is if one's technique falls short of what is required by the music...
For myself, I don't know of which I have more, but I do know that I fall short on both accounts and that I try to continue to grow in both areas. As for which I prioritize, it is the music, because without knowing what the music is, we do not know what technical means are needed to achieve it.
It goes without saying that any professional pianist should be able to play scales, double notes, etc., at a reasonable tempo.
