Coming from Malaysia I have the privilage of having both tables side by side in the billiard hall and to change cues and play both at once

. And most likely lose both as my brain will get stuck at some stage...
What many UK and US posters will find hard to understand is that many cueists in Asia play both games quite decently. National players of countries like Malaysia, Thailand, Philippines are very good at both.
Reyes was a SEA games gold medalist at snooker back in 1987 so he definately knows his way around a snooker table. Pagulayan played snooker at this year's SEA Games, Alcano was also on the team.
This is a bit of a silly question really. It's like asking is Karate or Tae-kwon-do better? Every art has it's pro and cons.
At recreational level I have to admit the average snooker player is better than the average pool player. When I come back to the pool table after snooker I sink end to end shots easily. Cut shots are an entirely different matter...
When a snooker player tries to snook me in pool by placing the cue ball behind something, watch his jaw drop when I hit a jump or masse. Try asking the snooker player to jump...
At higher levels it's different. That's why you have "pros". They're dedicated to their chosen games and rightfully good at it.
Anyway Jimmy White was in town last week. He can place the cue ball on a snoooker table better than anyone I know on a pool table. But he didn't win any pool title, did he?
At the end of the day, the main focus of any martial art is self defense. Master any 1 art well, you are a formidable enough fighter. In all cue sports is the point is to shoot in straight lines. If you can do that, you are good.
