I gotta say, I have done a fresh install on every Mac I have ever purchased and even consider it a vital privacy move*. When I got my most recent (2013) iMac, I skipped the fresh install and figured I would get to it later. Well, I never got around to doing a fresh install and for 7 years the OS was glitchy. It has always had weird lags and other spinning beachball joys that do not happen on any other Mac I use. The internal SSD failed this summer and I started booting from a fresh install on an external drive and have been glitch-free since.
To me, this is a lesson hard-learned. The next Mac and every single one after it will be wiped after unboxing and have a fresh install.
* RE: the vital privacy move ...
For years and years I have lived in South Korea and every store bought Mac had been already opened by the shop for who knows what. Fresh installs were essential. When I bought the the 2013 iMac, it was the first time there was an official Apple Store (online only) and I ordered from there. I think this is why I didn't bother reinstalling the OS.
