It seems like its a perfect distro. Rolling release so you get recent packages and dont have huge upgrades every few months, but not so bleeding edge that it breaks often. YaST is pretty cool but you are not forced to use it. Basic installation gives you enough essential stuff, but its not too bloated. The only thing its missing is AUR, but i still didnt find a program that i need and cant find in official repos or trough flatpak.
Honestly, now that i use it, it seems like insanity to install anything else. (for everyday desktop use)
Here are a few reasons I can think why some may not take to it. Trigger warning for Suse users
It’s not bad by any means, but I’ve tried it out several times and always ended up abandoning it because of little niggles like the above.
Software avaliability can be a bit scarce too, mainly when compared to fedora or even arch’s aur
Also it would sacrifice user experience over “security” - i.e. with default SElinux config proton may not work correctly - see this bug
Yast to me looks reassuringly old and sturdy.
yast can be ugly, but effective. And aesthetics are definitely subjective. Agree about zypper though.
