It is also first in the Distrowatch rank

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.
I’m trying a conversion from endeavorOS with CachyOS repositories, it was pretty seamless, I can keep my settings and endeavorOS theming, and allegedly you can switch back at any time. The cachyOS wiki has a short script for converting vanilla arch or endeavorOS to use cachyOS binaries. Been running for about a week and haven’t noticed any problems.
Did you notice anything that would be worthwhile switching from EndeavourOS to CachyOS? Not having any problems is nice, but is there an actual reason and do you even notice it in real world usage (I don’t count benchmarks)?
