I've used the Gripper Professionals, which are my favorite grip and the regular Grippers. I've also use the Presentation grips, which are the ones in cowarts post. I've never tried the Decelerators.

Which grips are best for you is going to be an opinion only you can answer. Everyone is different with different personal opinions and physical characteristics.

I've found that if you plan on shooting a lot of heavy loads a broader surface at the back of the grip will help spread the pain a little better than grips that are narrower. If you plan on shooting rapidly, such as for action pistol games, I prefer grips that allow my trigger finger to sit further into the trigger guard, which is why I like the Gripper Pros with the open backstrap.

I know exactly what you mean about the Hogues, I hate them. At least until I work on them.
