The Wii for sure because I loved how you could customize your main screen (and subsequent screens to the right) with your favorite titles. I don't like that Switch/2 just shows what you played last on the main screen but I do love the group/folder customization, so they would be my next favorites. I wish you could at least go to groups immediately when you select "all software" though.
The WiiU would definitely be last because I hated that Miiverse came up on your TV first. If it had allowed me to have the games menu on both the tablet and TV simultaneously instead of that Miiverse junk at all it would have been great.
