I used to buy Pearl Izumi Elite Gel. I liked them at the time, but the padding flattens out quite soon. I switched to Giro Strade Dure Supergel last year, and they fit my hands very well. Pretty durable, they are more than a year old and still good. My local bike shop has them. I like that the hiviz is on the top and on the palm side for signaling turns.
I had to try on different gloves brands. Some just didn't fit me at all.

Fitting:
Reducing excessive hand pressure on the bars will help a lot. I really like this easy test to see if the saddle and bars are set correctly: Set saddle fore-aft position.

I have my bars set high enough that I can use the drops comfortably. It's a huge help to be able to switch back and forth between drops and hoods. Riding in the drops helps a lot on rough roads, spreading the force over my whole palm. And the aero benefits are nice, of course. In the drops, my back and core are carrying a bit more of the load, instead of my arms and shoulders doing all the work.
