From what we've seen so far, the UI from Switch is a significant improvement over the HOME Menu of both 3DS and especially Wii U.
The problem with the 3DS and Wii U UIs is, accessing anything else than the games is a often pain to deal with. A good amount of the features that would be frequently accessed seem to be tucked further away than they needed to, some of which are buried within apps.
While both of these platforms share these issues, the Wii U dropped the ball even further. Even after several updates, the overall interface is not only unreasonably slow and convoluted, but also poorly thought out at times. Why can't I get rid of the WaraWara Plaza that gets shoved in my face every time I reach the HOME Menu? I don't care about those low-quality Miiverse posts! What's up with all of the long load times while navigating through the menu? Why are plenty of important features still buried inside of apps? Why does System Settings force us to use the GamePad, even though any other controller should be fine? Why won't Data Management let me copy just the saved data as opposed to the entire game data?
The no-nonsense and efficient approach of the Switch UI ensures that the player won't waste time figuring out what icon/button does what, and never suffer from sluggishness. Everything the player might need to access is laid out pretty clearly and won't take too long to load. That's certainly going to lead for more more impromptu gaming sessions.

My excitement for the console release tomorrow is getting through the roof
