I have both. The 3DS might be one of the worst Nintendo platforms I've ever had (not bad, just the worst of what we got). Luckily for the poor thing, CFW gives it a whole new life with a plethora of emulators and options and in the end I'm very happy with it.
Wii U on the other hand is probably the home console I played the most in my life. It's a shame most of its games are now on the Switch, because that means less reasons to turn it on again. But since it's backwards compatible with the Wii and it still has many games I like to play like the HD Zeldas, Tekken Tag 2, ZombiU, Xenoblade X, Pikmin 3, Super Mario 3D World, Star Fox Zero, Affordable Space Adventures... and a very robust selection of classic games within the Virtual Console... It's a console I come back to every now and then.
