Debian is pretty plug and play. Ubuntu tries to be idiot-proof like Windows on top of it. If like most people you don't do your own tech support it's a non-issue for the most part. Either way you take it to the guy who set it up if something breaks or needs changing.

Gaming would be the exception where you still need Windows. It's getting better but support is not universal.

Then there is another aspect: if you can’t speak english most good sources for troubleshooting are out of your reach.

Yeah, I could see how that would be hard.
