I cancelled my subscription. The sound quality is superior to Spotify (wasn't as convinced with Tidal), but everything else is inferior. Buggy apps, buggy API/database (search says three releases available, artist's page is empty), incomplete catalog, and too little improvement since I joined to justify paying 2.5x the price of Spotify, which just works. If Spotify would just add hi-res support and for the same price as Qobuz, Qobuz would be dead with hardly any hope to ever catch up.
I'm tempted to say I'll check back in half a year, but I doubt that's enough time.
