@stefanoStefano Marinelli openSUSE has come a long way. My first experience with it was SUSE Linux Professional 9.3 back in 2005. Desktop Linux was still in its early stages then and it did alright. A little buggy in some places but otherwise OK. I used its enterprise variants over the years, rather enjoyably.
I used it again briefly on another build in 2013. Just after restoring my data into a freshly installed system, the OS locked up *hard*. After the reboot, everything and I mean *everything* I had just restored to /home/pete was gone. Including the rest of my profile. The directory was empty. I went back to Debian as a daily driver and didn't touch openSUSE for almost a decade.
I decided to try both Tumbleweed and Leap 15 on a spare laptop. Yes, both are stable and have improved over the years. I prefer Leap over Tumbleweed. Unfortunately, due to that one data loss experience I am skeptical of using it (as a daily driver). I hope you have a much better experience with it.
