If forced to choose between tab or glove, it's the glove,  but I only wear one when shooting something over 50lbs,  or with a skinny,  high performance string....  With B-50 strings on my bows that are under 50lb draw weight, i usually don't wear anything.  In fact, I actually shoot better with my bare fingers.  If you shoot a little every day, your fingers build up to it, like my guitar callouses on the other hand.  Then there is one less thing to keep up with...  I shoot almost every day, so what works for me might not work for everybody.  To each his own....
