Manjaro
The KDE edition isn’t Manjaro’s flagship desktop which is why the distribution is more open to embracing non-KDE apps. That said, with the exception of mainstream productivity apps like LibreOffice and Firefox, the distro is chockful of KDE apps. Manjaro is a fully rolling distribution and the developers ensure their users are among the first to sample the latest release of the KDE components including the Plasma desktop, the Apps bundle and the Framework. Manjaro is also the only distro to bundle the Kleopatra tool to manage certificates. The distribution has its own set of custom tools bundled within the Manjaro settings manager that assists users with administration tasks such as switching between available kernels. Manjaro is also visually pleasing and its interface is polished enough to maintain a consistent look.
