Whatever your comfortable with. I'm right handed but can use my left hand with around 50% effectiveness.
I play golf right handed but putt left handed. I pass with my right foot yet hit pens/free kicks left footed. I can play tennis just as well (Or bad tbh) with either hand.
My advice would be to stick with what you've been playing with but dedicate a very small amount of your time with your weaker hand (Whatever you feel this is) as there are big advantages.
Always play snooker with a smile on your face...You never know when you'll pot your last ball.
