Which KDE Plasma distro is the most stable for everyday use?

BigLinux is impressive too—many users find it polished and user-friendly. It's another one worth considering if you're exploring your options!

Kubuntu is another favorite among KDE users. It offers a good blend of stability and up-to-date software, making it a solid choice for your studies.

Debian is often praised for its stability, though it might be a bit slow with updates. It's a solid choice if you want something that just works without too much hassle.

Have you checked out Fedora KDE? It has better software compatibility than some others, and although the updates are a little slower, it's still reliable.

If you want a distro that comes with KDE by default, OpenSUSE is a great option. They really support it well and it’s widely used for everyday tasks.
