Not even talking about the switch portability but I think there must be people out there who only have a Nintendo switch to play game and if they wanted to play mk (and not buy a PS5/Xbox) then there was only one option left… Sad thing is that they didn’t even release it to the PS4/Xone gens console.
Buy one for the living room, oled or standard. Then, if requests / frustrations about playing asynchronously piles up. Consider buying another for the most invested of all. Take physical copies also. They’re easier to share.
