So many options nowadays to play games. You really need to work out what games you want and if you need portability. wii u runs wii u and wii games plus gamecube games and emulators for older systems if you homebrew it. Graphically its not far below Switch. You could also ask the question is it worth getting a 360, ps3 or other older system if you have never owned one and experienced those games.
I certainly feel its a better gaming system currently than Switch and that might be the situation for a couple of years in my opinion anyway but then portability isn't important to me. Just because a console is being supported with new games doesn't automatically make it superior to a console that already has a wide range of highly rated games because if you haven't played those games they would be new to you anyway and this is especially true where the performance level of the consoles is very similar.
