I too actually kind of enjoy setting up a new "clean" iPad. Did if with my new 12.9 IPP. I have done it so many times with phones, computers, iPads, I am just used to it and it helps me to re-learn things I have forgotten. It gets easier...
Agree, though with a version upgrade of iOS you sort of have to go through Settings, top to bottom, to see what's new and what settings have toggled to a setting you don't want, even if you don't set it up as new.
