Not the author, but I just tried KDE for two weeks, and coming from Gnome, I couldn't acclimate. I found the Plasma experience unpolished, inconsistent, and prone to error. I also ran into quite a few bugs (at one point, Plasma just stopped giving me window previews when alt-tabbing, and not a single alternative alt-tab style from the built-in installer worked for me).

Two examples of things I missed coming from Gnome:

- I really appreciate the gnome-shell's unified "Activities" overview: I tap Super and I get a single experience that combines Plasma's Quick Launch Bar, Present Windows, and Desktop Grid features. I find that to be a faster, more fluid experience than the Plasma equivalents.

- KWin expected me to resize windows by, somehow, hitting a border that's exactly 1 pixel wide. I evidently don't have the motor control to do that quickly or reliably. Gnome adds a ~10 pixel wide invisible border to each window which is quick and easy to hit regardless of input device.

That's not to say everything is all roses in Gnome land, either, but what's there just seems more reliable, consistent, and intentionally designed. Still, there's no panacea. I wish Gnome's screen zoom was half as fast and fluid as Plasma's. I wish Gnome still supported desktop icons. And AppIndicators. And a 2D grid of virtual desktops. I wish Gnome felt as responsive as Plasma.

I'm planning a switch from Fedora to OpenSUSE later this year, at which point I'll give Plasma another shot and be more diligent about recording and reporting bugs I run across.
