Hi Win,

My own take, both of them give you a clean install of windows... but one method is a little cleaner and more full proof.
A reset usually works, and you’ll have a new image of windows ready to go. That being said, it doesn’t completely wipe your drive and start from scratch, it kind of lays a new image on top of the old one.
A clean install, allows you to wipe out all the current partitions, create 1 new one, and install windows.
Hope this helps!
