Some are good, some bad, some terrible. Everybody has a different take on it.
If you have to wear gloves, you're probably playing too hard. However, I've made a career of playing too hard, so I'm not one to talk! When I need drumming gloves, I go down to the local golf shop and buy two Foot Joy golf gloves- one right, one left, since golfers inexplicably wear only one glove.... They are expensive, but they are *very* tacky for grip enhancement, and once they're wet with sweat you really can't even feel them on your hands. The thinner the better, I say... I've been using them since 1980, which was back before anybody made "drumming gloves", and they work for me.
I did try a pair of the modern drummer's gloves in a store one time a few years back they were thick, slick, and stiff, which struck me as being a losing proposition. You want some skin protection and some additional tackiness for grip, but you can't afford to lose *any* sensitivity or dexterity (especially if you don't play that much). Maybe they are making better gloves for drumming these days, but I sure wouldn't have used those.
Try them both before you decide!
