Peoples' hands vary and so do shooting styles. I shoot 3 under, but it's really 2 finger under and one on. I pull primarily with the middle finger and index finger. My ring finger just sort of rests on the string, but no deep hook with it.
I experience no finger pinch, even with an ultra short Two Tracks Ambush, but since all the string weight is on just two fingers, I like more protection than a lot of people.
If I were still working, I'd bet a paycheck one type of glove wouldn't satisfy everyone regardless of how well made it is.
I love my (now discontinued) Alaska Super Glove, with the hard, Cordovan finger pads, but many would find it too stiff and lacking in string feel.
