I haven't used the Linux client in years, so I don't know if it's on par with Windows/macOS versions, but I imagine the biggest selling point is downloading your playlists/library for offline listening. Plus, IIRC, the web version (and third-party clients) don't allow listening to the highest quality versions. I'm on mobile, so I can't check.
