Gloves are basically a solution to a problem.
If you don't have the problem, then you don't need one.
But if you do, they're a godsend.
I wore one for years, I got a lot of chafing on my bridge hand. I just had a weird insight...
I think that's why I use open bridge so much, and my closed bridge is fairly loose and sucky.
After a while I just didn't need it any more.
Part of it is... when you get a cheap cue, it has a shiny sticky finish,
not unlike the Clear-Coat on a car. But later when you get a nicer cue
(or in my case an LD shaft) it's just smooth, finished wood.
I also sweat less while playing. Maybe as you improve, you simply are less nervous
and indecisive about shots, and literally 'stop sweating it so much'.
I would not hesitate to recommend a glove to anyone, even though I no longer use one.
