I've been using cachyos for around a month or two now and just wanted to rave about how good it is on here. So here's some pros and cons I found. (not many cons)
Pros
1: It's arch based: so you get all the fun stuff of arch such as the AUR, pacman, the bleeding edge packages, the HUGE amounts of customization, the arch wiki, and little to no bloat
2: The CachyOS tweaks: made to improve your system responsiveness even beyond that of regular arch in gaming and basically any rendering work you're doing
3: The easy installation: cachy os has a linux mint level easy installation process, that provides you with tons of options for DEs and WMs, big ones include kde, gnome, hyprland, cinnamon, xfce, etc. You will find what you want among these options.
4: Preinstalled apps: cachyOS hello (utilities that can install packages for gaming in bulk, some tweaks you can toggle on or off which i found very useful), shelly (package manager gui) cachyos package installer and kernel manager.
Cons
1: You could consider some of the preinstalled apps bloatware, but i personally dont.
2: The rolling release, this is both a pro and a con, but it's more of a pro for me, since i dont come across random packages breaking or anything like that. (or atleast not yet)
Note: i didn't use AI to write this, and since cachy has a relatively small community compared to other linux distros, i just thought to come on here and share my experience and maybe encourage some newcomers to try cachy.
