I've seen this thread around, though haven't been involved much, so I guess I'll 'add'.
I've been using Linux for just under two years now. I'm currently typing this on my laptop running Manjaro KDE. A desktop at the house is currently running Ubuntu MATE (but not for long, that's up in the air.) Another laptop is running Solus, and another is running OpenSUSE with GNOME.
If anyone's interested in the history there, I'll brag that it was an instant transition to Linux. I moved from Windows to Linux immediately with no contingency plan. I started by installing Xubuntu, wiping my HDD on an HP 2000 Notebook. I hopped from distro to distro for a good six hours, and never looked back. I used Linux Mint 17.3 with the Xfce desktop for about 10 months, toying with other things in the meantime. I'm really loving KDE, though GNOME used to be my favorite DE to run.
Oh, I'll let you in on a little secret... I'm actually a huge fan of Solus. Who would've thought...
PSPSPS: My distro is better than your distro... lil bitch <3
