Actually, I used to agree with this but I've changed my opinion of it. If one aims better naturally, then yeah, use that in your decision making process. Simply feeling better though, IMO, is really irrelevant. I can't say that my Glock feels "good" at all; it doesn't feel wrong or anything, but I don't know I'd ever choose it if I were going by feel. I'd probably take my CZ all day, every time, if I went by feel. In fact, I get a sore thumb knuckle darn near every time I go practice because the Glock just sits in my hand in a manner that it hurts my first thumb nuckle after enough rounds fired. My thumb is totally sore after a class, where I'm going through multiple hundreds of rounds in a few hours.
All that said, I'm not carrying my Glock for fun, nor is my range time with it 'fun' shooting time. I train and practice for that one critical incident where I am forced to respond to a threat. In that case, my sore thumb knuckle will not be a factor at all. I am, of course, discussing this with relation to a weapon being purchased for the purpose of being a fighting weapon, not a range fun toy or any other purpose.
