I tried Gecko Linux Rolling once, and didn't have a good experience. For starters, I couldn't find the way to update the system on Yast. I admit my Linux skills rather low, but I have used other rolling distros (Manjaro, Antergos, PCLinuxOS) and updating them was very very easy. Since I couldn't make heads or tails of Yast, I decided to use the terminal instead. I entered the Zypper update command on Konsole, restarted the computer, and it didn't boot anymore. I decided I had had enough, and that was the end of my story with Gecko.
If I had to say something good about Gecko Linux, is that the ISO was light and was not bloated with packages I will never use, unlike Opensuse, which is very bloated.
