With me it depends on what I use the gun for.
J,K and L frames that may be carried or mostly fired double action usually wear Uncle Mike's/Butler Creek grips. I'm not a big fan of rubber, but these grips fit my hand perfectly for DA shooting and they're inexpensive. The snubbies use the round butt boot grip while the 4" guns have square butt Combats on them.
Sadly, these grips have been discontinued. But they can still be found new in the package on some of the auction sites.
The N-frames that are often shot DA mostly have whatever I can find that fits my hand. I'm fond of Herrett's Shooting Stars, but there are couple of others as well.
My Model 29 is the only gun I have with Pachmyers on it and that's just to tame the recoil. Otherwise, I don't care for Pachs.
Target guns or those fired mostly single action wear factory Targets. They work for me and keep the guns looking original.
Collectables and guns that don't get shot very often have whatever originally came on them. In some cases I've had to find correct stocks to replace what was on it when I bought the gun. Several of these that came with Magnas have had Tyler T-grips added for better shooting.
There really is no correct answer. So just find and use what works for you.
