I've had Spotify for years and recently tried both Tidal and qobuz.
Easily transferred my spotify songs with both services.
The only reason I'm sticking with qobuz is that it seems to automatically keep all songs at same sound level during playback. With Tidal I either had to volume up or down between songs. I may have missed where you can do that on Tidal but it was automatically done on qobuz.
I don't here much differences in sound quality between the 2 formats. Using avm 90 and eversolo dmp-a8.
