I find Qobuz much better SQ on my reference system, very highly resolving with lots of digital bells and whistles, e.g., network switches, fanless silent mini with optimized settings, LPS, great DAC, balanced cables, big tube amp with lots of headroom, and 99dB speakers. Qobuz Interface however SUX.
Amazon HD good enough on my other four rigs, great interface, great recommendation logarithm, new releases drop quicker, more “fun.” I actually look at Amazon on my phone to select content to pick on Qobuz! Qobuz bigger deeper soundstage, more stereo separation, depth, and detail.
Haven’t tried Tidal, but based on thread sounds like Qobuz better SQ, pun intended.
