To me, the best grip is like the best saddle in that you should never notice it while you are riding. It should feel natural. I really liked the grips that came on my Yamaha Cross Core, but I gave them to my wife because she gave hers to one of our granddaughters, (long story). I put on a pair of Cork Ergons that we had laying around. I did not like them, (to be fair, they were size large, and with riding gloves, they felt too large and I noticed them a lot.
I decided to give the SQLabs 710 Grips a try. I found the shape of them very distracting at first, (they are not round). They felt fairly normal by the end of my first ride with them. The next ride was the same, (started out feeling strange, but ended the ride without noticing them). Now, after a couple hundred miles with them, I don’t notice them at all. They provide a good grip and stay comfortable. I always wear gloves, and the grip with gloves is very good, (although with the heat today, my bare fingers found them to be a little slick, but no more than many other grips). The inner bar ends shown are not SQLabs. They are an old set of Specialized Carbon bar ends.
I recommend the SQLabe if you ride with fingerless glove. You might find them a little slick if you ride barehanded. It wasn’t love at first ride, but I do like them now and I have no plan to replace them any time soon, (unless I can get a pair of the Yamaha grips again)
