I distro hopped to it from Bazzite a couple of months ago, and I could not be happier.
If you try the installer, be careful when selecting multiples DE/WM as the conflicts were not listed anywhere for the installation process.
Picking a single environment and then adding the others later was what worked for me.
What’s the difference between this and a fresh install of Arch with a DE like KDE/Gnome?
I’ve been using Arch for so long now that if I bought a new machine I would find it hard to try anything else.
I think it’s aimed more at newbies than seasoned veterans like yourself.
