Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
Every couple of years I give KDE Plasma a spin, and I’ve found it disappointing every time. Nothing terrible, just a lot of tiny bugs and inconveniences. I find it strange that it gets recommended as a beginner DE so often just because the layout resembles Windows a bit more. Gnome is so much more consistent and aesthetically pleasing… not that I use it, but it’s always my strong recommendation for beginners.
Good luck on your Linux journey!
