@juergen_hubert Nice! Then it really depends what you're comfortable with. How much do you want to poke under the hood of your system VS just wanting things to work?
Oh, Ubuntu and its variations are also very beginner friendly. My kids use Kubuntu for games and school and have had virtually no issues.
There's also a difference in Linux between the OS and the Desktop Environment that you use to interact with the OS, so if you like the interface your Debian colleagues are using, you can ask them what it is and use it with other versions of Linux.
Gotta run now, will be back!
