Let's analyze the situation even a bit further: Switch stock is suffering perhaps even greater shortages than Wii did in key areas, and Wii released around the holidays. You're comparing a system released in March with one released around the prime time of console sales. People keep forgetting this crucial fact. Switch doing this well from march and up is pretty insane.
Nintendo is directly competing for parts with Apple and others as well, Wii didn't have this issue to my knowledge. Nothing near on Apples popularity anyway, which gives Apple priority over Nintendo in getting those parts. That's why I believe the stock situation is even worse for Switch right now.
When you look at the full picture, Switch may have even more appeal strength than the Wii potentially (not for certain in the long run, but possible) That isn't too far fetched either, as Nintendo handhelds have always/usually had close to or even greater appeal than even the Wii did. The main hurdle for Nintendo is whether or not they can meet demand before people lose interest.
