If you’re wondering about Fedora vs CachyOS, it comes down to what you do on your PC. And what you’re used to.

If you want better “preconfiguration” for graphics stuff, CachyOS is the way to go. With Fedora you will end up referencing and maintaining a whole lot more yourself, while the CachyOS maintainers basically do all that maintinance and config optimization for you.

But Fedora might be better for a less GPU-focused “workstation” type system.

Generally, I’d look at the “style” and interests of distro maintainers. CachyOS is built by a collective of linux gaming/compute enthusiasts that snowballed into popularity, though it does inherit all the work from Arch. Fedora is a long standing workstation/server workhorse, a “pre release” for Red Hat enterprise linux.
