Obviously TP, Shabi, and SJay are the resident limit experts (if we include Kurn, he'd likely be up there as well)
Me and JD are the experienced Cash NL players (not saying the best just experienced in medium [me] and high [him] stakes)
I think Mayhem belongs in the NL group, but he doesn't post enough of his HHs so he gets excluded
SNGs are tough to say, I don't think any of us play enough of them or post enough about them
MTTs TP and JD have the best track records
