I continue to use Qobuz exclusively.
The Qobuz UI is indeed BLEAK. Worse than useless, in my opinion.
However, I use Qobuz via Roon, so the UI is a non-issue, except in the car. I stream through a Linn Akurate System Hub in my main home system and through a Bluesound Node 2i in my second system, and I am very happy with the SQ in both setups.
I have not used other services, so I cannot speak to the Qobuz catalogue relative to other services. With a few notable exceptions (ZZ Top Deguello and many Telarc offerings), however, most of what I want is there. The Telarc omissions are indeed regrettable (but I wonder if the other services are any better in this respect), but I have most of the Telarc I want already ripped from CDs onto the HD in my Roon Nucleus.
I am very happy with the Linn/Roon/Qobuz setup and not itching in the least to do something different.
