Not to sound too pretentious, but I am proficient enough at my instrument that the shape of knob doesn't effect my performance.
I pick whichever one looks coolest
Not that I doubt your talent, but really...that's like saying you're proficient enough at walking that it doesn't matter whether you're on a 20' wide street or a 1/4" wide irregular beam.
I've been playing for 65 years and find that some knobs definitely affect my ability to "work" my instrument.
I most certainly must not be as good as you.
