I like CachyOS very much. They care a lot about optimizing Linux for desktop usage and shipping the latest and greatest.
On one hand that is very convenient because they apply 95% of the settings I would do manually anyway. Spares you a lot of Arch wiki reading. They also offer a lot of kernel options with different schedulers and run their own CPU-architecture optimized repos.
On the other hand they ship kernel 6.11 right now, while it is still in Arch testing. Or they ship mesa x.0.0, while Arch usually waits for x.0.1.
In my personal, subjective experience the perceived desktop performance is outstanding, going so far that other distros feel “slow” now. But the cost to that is it introduces a new edge to Arch, an edge that is dulled by projects like EndeavourOS.
So if you’re a person who tried the Arch zen kernel and judged it equal to the standard Arch linux kernel - “This is fine” - there’s probably nothing CachyOS has to offer to you.
