UX for what? Web interface? Desktop two-way syncing 'folder' and shell (context menu) integration? I enjoy the web interface for Box the most, followed by OneDrive's visual design, but not performance. Google Drive's user interface outperforms OneDrive's in my subjective opinion, but file manipulation options can be a bit obtuse. I have no experience with other cloud drives. As for shell integration, they're universally garbage. Two-way sync is default and there is no way to enable one-way sync (in either direction). It fulfills a simple use-case but there's no way to configure it otherwise with the stock sync apps.
