Excluding BC and VC (inc PSN and XBLA ports) SNES is by far the best.
If you included them, then Wii would win, simple cause you have access to all console based Zelda games (between both GCN bonus discs and LttP on VC) and I think all main console based Mario titles currently. But its status would be an assuming the best/your favourite of "x" systems games came out on VC.
