The most ironic difference? MR controls both, in snooker they have snooker people running it, maintain traditional rules, traditional ball colors, traditional cloth color, and they play on and with the best equipment available.
In pool, well we got Emily, complete rule changes, equipment pocket size changes, non traditional ball colors, non traditional cloth colors, and for most of their events, play on shite low rent tables and bargain priced balls. All you need to do is offer Em a large sum of money and your crap can instantly become “The official (fill in the blank) of the WNT”.
So in synopsis I’d say a direct lack of respect from MR for pool is the greatest difference.
