Pool and golf are alike in three ways. The ball doesn't move until we strike it (so it's not reactionary, like other sports); there's no opponent (playing against yourself); and the swing is a circle, where we want to strike the ball at the bottom of the circle. More professional instructors in both sports recommend looser grip over tighter...particularly the better ones.

Golf and pool are not the same, but many are referencing it because there are similarities.
Spend enough time in golf and you will meet or read about proponents of a soft and firm grip. No one recommends a death grip, but plenty of instructors and pro's advise a firm grip, say a level 6-7 on a scale of 1-10. Others recommend a softer grip. I spent a lot of time using both.
For myself, a firm grip worked well because it was a lot easier to maintain a consistent grip pressure throughout the swing. This was extremely helpful when playing under pressure and on full length shots where the natural tendency is to grab harder at the transition.
A firm grip also made my swing less "handsy", which led to more consistency.
As a newer pool player, I am experiencing similar things as I did in golf.
