Depends a lot on your bumhuting skillz. If you table select really hard then your obviously going to get a better winrate on regular tables. Overall there's better fish/reg ratio on standard tables and the fish are worse since they generally play looser then zoom fish.
On the other hand you get a lot more volume in playing zoom, you don't have to lose focus table selecting and it easy to put in short sessions while on standard tables you pretty much commit yourself to 2h+ sessions since it takes 30mins to get good tables going so its pointless to play short sessions.
Personally i play nl100 both FR and SH regular and zoom, depend on how much time i have available and what i feel like playing. My winrate is slightly worse on zoom but since i get more h/h my hourly is basically the same.
