Plasma/KDE is mostly great, but a major thing that GNOME and Xfce still do better is GVFS and GVFS-FUSE. That means I can browse to smb://something or sftp://something, double click a file and it just works whatever the application is (e.g. play in VLC, edit in VS Code). This has never worked in KDE where only KDE apps can open remote files (and even that has bad performance).

GVFS/GIO is nice, but at least on LTS, it can be a bit rough (with i/o errors under load, at least during PhotoStructure imports). Also, somewhat frustratingly, the GIO system mounts network file systems with paths that include a colon character, which breaks standard PATH parsing.

KIO is also gaining that capability.
