Wii U sell is it worth it?

I wanted to ask if it's worth selling my Wii U because the switch is already there. And if I sell the Wii U how much money would a good price be? I own the Wii U Mariokart8 Premium Pack and another 1x Pro Controller 1x Mario Maker special pack with the Artbook and the game Minecraft Wii U Super Mario Bros U Paper Mario Color Splash and Yoshi's Woolly world Mariokart8 is preinstalled. I would appreciate an answer because it would be too bad if the Wii U dusted in the corner.

In your place, the Wii you would keep. The Wii U has a lot of great games that you should definitely have played. But if you've got it in your head to sell your Wii U, with all the trimmings anyway, I think it's about 350 Euro for a reasonable price.
