Qobuz or Tidal?

Even Spotify Premium sounds better to me than Tidal even with a proper MQA unfold.

My subjective impressions of the musicality and sound quality of the major HD streaming services: (as of November 2020)
1. Qobuz
2. Primephonic
3. Spotify Premium (320 kbps Ogg Vorbis which is not lossless)
4. IDAGIO
5. Amazon HD
6 Tidal

I started with Qobuz a couple of years ago but decided to add Tidal because some titles were missing in Qobuz.

If you can afford it better to have both IMO.

I mostly do streaming with a Roon Rock NUC and HQPlayer core.

"better to have both IMO"

I agree with @thieliste and play music using both of those services, plus my ripped/stored CD files (flac) through Mojo Audio's DejaVu streamer/server.  Roon controls whatever I play and I find the sound quality between the three sources mostly indistinguishable through my system during normal listening.
