I mean i'm currently in a learning process with Linux, i would like to be a power user like in windows, but i'm just not yet. I don't know if i would say disappointed, but i tried to use KDE first and would say my experience was rather bad, it was a bit buggy here and there and i didn't found out how to fix my problems. I'm surprised by it because i though i would like KDE for sure more, but i'm happy i switched to Gnome. So as the op said, part of the experience is choosing the right distro or in my case desktop enviroment is part of the experience.

Sure had few driver issues, or installing japanese was a bit of a struggle, but i have fun solving problems.
