I wouldn't recommend CachyOS personally. If you wish for a distribution with a traditional read and write filesystem and new features and package versions I'd recommend Fedora, which I always end up going back to.
Personal preference, but I like my software to have as little patching or customisation done by my distribution as possible, and to be able to use it as upstream intended. This is a longstanding benefit of Arch Linux, but CachyOS goes beyond this to kit out a default install with garish themes and shell configurations to the point that the default user's login shell gets set to /bin/fish.
Some fume was had because I really do not believe that Shelly is a good choice for the primary system package manager. It's written in C# and compiled with .NET AOT and I just cannot shake the sense that it is an incorrect choice for a core system program.
The GUI needs a little bit of polish, but the command line user interface is terrible; there is a DNF/APT style subcommand interface which has no search subcommand, and other features are split into a Source->Action->modifier "shortcode", but that is very different from Pacman. The action letters differ between sources; for example to search repositories you use "-SQa" but to search the AUR it is "-AS", and I believe that it is like this for the sole reason that no thought has been put into it. I'd also suggest that the authors have little experience with Unix and so it isn't made with the same kind of attitude. There are other things like table wrapping at 80 columns making the output unreadable and lack of a package download counter.
When I brought it up to the "community" I was relentlessly flamed for not being entirely positive about this change to the distribution. I'm of the opinion that the maintainer had her feelings hurt because I criticised her project, and lied about the issues I had raised. A pile on ensued.
The final straw for me that made me dump another 24 hours in moving distribution again is that the attitude of the CachyOS project can be summed up as "script kiddie" and the "community" spaces are populated by and large by children. Despite having the same sort of audience Bazzite has a much more pleasant community. Fedora seems to avoid all of this kind of nonsense, I suppose by dint of being run by professionals, and avoiding Discord.
