Arch based distros are easy AF. I’ve been on Linux for 2 years, I’ve tried 10+ distros, and Arch has been the easiest for me, and stable as it gets, while allowing me to get the latest drivers needed for gaming.
I’ve been using Crystal Linux, but got tired of it’s CLI only package helper, and since then I’ve moved to Manjaro KDE.
Whatever you chose, make sure you get automatic BTRFS snapshots, so you can roll back at boot whenever you wreck it.
I’ve read here on Lemmy that NixOS is a great concept but the execution leaves a lot to be desired, stating that it’s overly complicated and documentation is lacking.
If you only care about stability then you should go with Debian. If instead you want something that limits you so that you can’t easily wreck it, you could use an immutable distro like Vanilla OS, Fedora Silverblue, BlendOS or Ubuntu Core Desktop.
