I use EndeavourOS. I like pacman and AUR, as well as the fact that Arch-based distros are well-supported by most software. I'm too much of a noob/too lazy to setup an OS without a GUI installer though, which is why I prefer Endeavour over Arch.
I use it too, it’s great. I’ve been using Linux for decades and I know it intimately but why waste time fiddling with installing when Endeavour OS can do it with sane defaults while I brew a coffee ‽ I recently got a new laptop and I was ready to play Baldur’s Gate 3 from the old SSD in 20 min.
I did spend a minute installing btrfs-assistant and btrfsmaintenance though, it’s nice being able to boot a snapshot from grub just in case. I could probably have grabbed Garuda Linux instead but I’m happy with Endeavour.
