For critical listening I prefer Qobuz. I like the fact that I can listen to hi-res files and don't need any proprietary equipment (hello MQA) to do so.
Tidal does have a bigger library and the MQA files do sound good, even with a non MQA DAC (I have both). If I can't find something on Qobuz, then I'll go look for it on Tidal and can usually find it.
I also have Spotify and Pandora for less critical listening (background music, in the car, etc.) Spotify does a better job of putting together playlists based on my musical tastes than Tidal and Qobuz doesn't currently have this feature.
For me it's not a matter of either/or, I use them all based on their strengths.
If Qobuz's library expands to compete with Spotify and Tidal and they provide custom playlists on par with Spotify's, then I would probably go with Qobuz only.
