Sure it has a couple of bugs but it has been super solid. I'm on KDE Neon which is the least stable Plasma distro and I barely notice bugs. Once a month Plasma crashes but it does a full recovery with windows in the exact same places.
Gnome is currently the least stable major desktop. By far. It's an absolute disaster crippled by tons of little bugs that creep in when you least expect them. Even if you don't add anything to it and use Gnome as vanilla as you can get it, it's still going to be problematic.
Plasma has some small bugs here and there -- and there was a point a few years ago when Plasma seemed like they didn't care about bugs and instead just threw out a ton of shiny new pointless features every release instead -- but recently it is incredibly solid in general and more usable than anything else in Linux, by far. One of the only things I find "buggy" about Plasma is when someone tries to over-rice the desktop with tons of widgets and other things everywhere.
I really don't know how you could call Gnome buggy, Gnome is super stable.
You can just compliment Plasma without shitting on Gnome you know.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
