I would recommend you Aurora or Bluefin. They're both the same, but one is KDE, and the other is Gnome.
They are pretty much indestructible, ultra-low maintenence (staged automatic updates, etc.), different branches, great quality of life tweaks and more included.
It's a bit similar to how Android works, but powered by a common PC.
With the great touchpad both KDE and Gnome would shine due to their smooth gestures they offer.
