Re: Why OpenSuse?
Welcome to Opensuse & its forum.
In my case I came to Opensuse from Ubuntu,not directly but from there.
The 1st thing for me was that I felt uncomfortable with the use of sudo in Ubu. I had fears that doing sudo this & sudo that it was only a matter of time before that password would get known. Since Ubu has only the one, rightly or wrongly it bothered me.
In Opensuse I have the security of a root password & a user password it makes me feel better, once again rightly or wrongly.
The 2nd thing about Opensuse its flexibility so far it has been able to handle anything I throw at it & do so in a way acceptable to me.
3rd thing is Yast it's a one stop shop for taking care of your PC. Ubu was kind of messy in comparison. In Yast you can do hardware, software, time settings, & well over time you'll get the idea.
As to Gnome or KDE yeah most of us are KDE users but don't let that bother you (see my 2nd reason). I personally am a KDE user BUT I've used Gnome in Suse & IMO it handles better here than in Ubu. However also IMO it handles KDE best!, but that's just me.
Enjoy your stay with OpenSuSe & don't forget to have a lot of fun!
