A tab has real world hunting application benefits that are often overlooked. With a glove, you better have in on, because you won't be getting it on quickly, if need be. With a tab, you can get one on in seconds and with little movement.
In addition, a tab is much nicer when on stand, be it treestand or ground hunting. I now hunt exclusively from the ground. With a finger hole tab I can flick it out of the way while keeping it on or easily remove it with no noise and minimal movement. Then I can take a sip out of the thermos, eat a snack, go thru my pack, grab a grunt tube and even take a leak if need be, all quickly and without having to take a glove off and on again.
For these reasons alone, a tab beats a glove and one should try to use a tab. For shooting, I started with a glove in 1978 and shot a glove for a long time. I also shot split finger. I now shoot 3 under with an Ol' Buff elk hide tab. The best 3 under tab made, in my opinion.
