I use Roon and Innous Sense as my music front ends. Regardless of front end, I find Qobuz better sounding than Tidal in general, but not by much. Using a PS Audio DSD DAC, I find little difference between Qobuz HiRes and Tidal MQA. I listen to Tidal most often because I like their playlist much more than those provided by Qobuz.
For critical music room listening, I use Sense because it’s sounds more natural than Roon. I’ve created playlists using a combination of Qobuz, Tidal, and songs stored on my Innous Zenith. Sonically, all of the music sounds good to me. As is the nature of digital music, some songs clearly sound better than others.
