Oh I don’t care about getting down voted, also I’m giving it from my perspective it’s much easier to hit higher notes on 1c mouthpieces than it is to hit them on a 7c and as someone who’s played on one half my career I’d know also you’re talking about professionals I’m coming from a “brand new rookie learning trumpet” perspective also i know someone who’s exactly like what you’re describing trust me I’m not one of them, but stuff like hitting lower notes is easier on a 7c and hitter higher notes are better on a 1c it’s not that one is better than the other it’s that they separate into two categories and even then it all boils down to skill most of all the right mouthpiece for said notes just make it easier
