I usually just do a full reinstall, it's faster, requires less storage, and it's more futureproof. I have my home folder at a different partition, so the files aren't a problem. Archinstall made this a lot easier, and i love it.
After being with my current distro and install for several years I've accumulated so many small changes and tweaks into the system that it'd take ages for me to get back to where I am with a fresh install. Snapper snapshots for life
