It's much easier to install Linux these days than it is to install Windows. And with KDE Plasma the user experience is really similar. As for the distribution I would suggest OpenSuse as that has very little requirement for terminal commands, they've packaged GUI elements in the whole distro.
As for Tumbleweed vs regular, that's up to you. I'm happy with Tumbleweed.
