I've shot a glove for nearly 50 years. During that time, I could never find a tab that felt comfortable. Finally did, a Black Widow calf hair split finger. I like shooting with it in nice weather on the range. Don't think I'm any more accurate with it than a glove, but I do seem to be able to get my fingers a little closer to the side of my face with it, feel my anchor a little better with the tips of my fingers, etc.
For hunting, though, I'll use a glove. It always takes me a little time, maybe only a second or two, to properly place the tab on the string around the nock. It has three layers of material and small flaps that protect the two fingers that touch the arrow. I often have to look at what I'm doing. With a glove, there are no "moving parts." I can look at the target and and position my fingers for the shot by feel. As G. Fred has written, "Things have a way of happening very quickly in the woods." A second or two can make the difference between getting a shot and not.
In cold weather, I wear a wool glove with the fingers cut off to fit over my leather shooting glove so only the stalls protrude. Keep my hands in a muff until I'm ready to shoot.
