Also making the switch from spotify.
Trying out Qobuz & Tidal - both seem pretty full-featured thus far.
Qobuz:
+ Works on OpenBSD
+ Downloadable/offline music
- Doesn't seem to have as many artists
- Might be a bit more expensive than Tidal
Tidal:
+ Works on most everything
+ Mobile Client is nice and 'just works'
- Doesn't seem to work on OpenBSD
