I've played way more Mario than Zelda, so Mario wins almost every time.
I might have to give 3DS to Zelda for A Link Between Worlds and Ocarina of Time 3D. At least if you count remakes.
Mario wins Switch because it has the best Mario game (Odyssey) and perhaps the best 2D Mario (Wonder). Even the Zelda duology on Switch doesn't quite match that to me.

Switch 2: 120 million (was 116 million)
PS4: 120 mil (was 100 then 130 million, then 122 million) Xbox One: 51 mil (was 50 then 55 mil)
