Oh that's a good question. I have an unlikely answer.
It's GameCube. Not because of its sales potential — Switch 2 will pass GCN lifetime sales before the year is through — but other things. GCN was the last Nintendo platform to get a lot of third-party "AAA" games during their initial launch window: games like Prince of Persia, Lord of the Rings, Splinter Cell, 007, Tomb Raider, Spider-Man, Medal of Honor, Tony Hawk, Call of Duty, etc. I see this beginning to happen on Switch 2, thanks in large part to Capcom, which, incidentally, was a big Nintendo supporter during the GCN era. Oh, and the Switch 2 box art reminds me a lot of GCN box art. Particularly the spine. Finally, they both have a Kirby Air Rider(s) game
