I use both. I shoot primarily with a tab, but have no right hand tabs, so if I want to shoot my right hand bow I grab a glove which I can use right or left. That, by the way might be the biggest plus of a glove.
I would second trying out one from someone else, but gloves and tabs are a bit like PCs or smart phones - once you use them for a while, they develop a personality to fit you but not necessarily someone else.
My favorite glove with cordovan fingers is no longer made, but I bought a spare and the original is still going strong 6 or 7 years now.
