Fedora Linux: It's your Operating System.

In all fairness I like both, but I have a pretty clear vision of how my desktop should look:

• I want icons to press to start my most used programs.
• I want these icons on the left of my screen, so they don’t take away height with is scarcer than width on any 16:9 screen
• I want a small top bar that gives me a systray and the time+date(yes, I forget if it’s not visible all the time)
• Nothing on the desktop, it’s for showing pretty nature pics only

Both GNOME and Plasma do a good job at that(gnome needs extensions) and I prefer GNOME‘s minimalism and app starter over plasma‘s start menu.

But I also have some workflow related things GNOME just can’t do. For example I like my browser to always start on the right half of the screen, maximised height but half the width of the screen. My console should start on the upper left quadrant of the screen and the lower left is reserved for either another console or the first one maximised to the left half.

Basically the DE has to conform to my OCD and plasma is great at that. I can setup programs to force certain sizes, positions and ignore geometry requested by the app itself. I can still adjust it freely, but I set default parameters so to speak.

So I use plasma. Also I think relying on a dozen or so extensions for my workflow in gnome is too fragile.
