Most modern distros are either new distro trying to have more modern sensibilities, distros based off of Debian, Arch, or Fedora, or occasionally original things that are okay with being superficially similar to one of those while doing things differently at lower levels. OpenSUSE is one of the few remaining distros from the olden days that has been independent and doing their own thing for decades without spawning a bunch of forks or dying off. If you want to try something even older and crazier Slackware is sure an experience.

Why? Because it works and is reliable. I've been using Opensuse now for ten years on a server and it updated through all the releases over the years without problems. The machine is getting retired now, though. But the replacement will get Leap again for sure.

openSUSE is one of the old desktop oriented distros. I find it somehow similar to the old glorious Mandrake (r.i.p.). Like it it's a European distro and both of them are relatively KDE centric and so also somehow similar to Windows. So the philosophy behind both of them is to be user friendly in the way you can do relatively much with the central configuration panel.

It's based on an enterprise Server distribution. This is why it works how it works.

Always has been.

But to be fair, openSUSE was my first linux distro after Windows and YaST had been helpful to me before I learned how to use console commands. And then I switched to another distro.

https://doc.opensuse.org/ is going to probably be your best bet

It's just what you're used to. To me fedora seems weird and I don't know why people choose it over opensuse. To me opensuse feels like home.

Also yast is great and I don't get why more distros don't have a similar thing.

And to update grub it seems the best command is “update-bootloader”

grub2-mkconfig seems to work fine as well. I just installed openSUSE Tumbleweed on a machine yesterday and used that to add some kernel arguments. I was not aware of update-bootloader at all.

Like what’s up with YaST?

Yeah, it's like an all-in-one launchpad for managing the system. I haven't used it much because I prefer using the terminal for most things, but it seems to work fine when I used it a bit (installing some repos and Nvidia drivers).

I installed SUSE after over 20 years and so far it's been quite a good experience. Very similar to the Fedora experience I would say, in the sense that you need to jump through some hoops to get Nvidia / non-free codecs and then after that it's smooth sailing. Let's see how it holds up in the longer term for me.

I must admit I've mostly been an Ubuntu user since about 2007. But switching to Tumbleweed was like a breath of fresh air. A lot of the things were different, but accumulated experience over years allowed me to feel at home. I used YaST once or twice, you don't need it at all.

I've actually come full circle (as of yesterday) back to SUSE. I began using Linux around 2002. My first two distros were discovered out of frustration with my horrible Windows XP upgrade experience. Long story short, my first experience with Linux was Red Hat (probably 2.*) and SUSE Linux (both purchased in boxes). Since then I've used Ubuntu, Debian, Fedora, Arch, Mandrake (memories), and just about every flavor in between. I've never messed with Gentoo or Slackware, but I've been around. That said, I'm currently finding my return to openSUSE to be a breath of fresh air. I may have rediscovered my new OS home (at least for a while). It's definitely different, but give it time, I suppose. It may grow on you... or maybe not.
