My $0.02... Qobuz is the first and only streaming service I have used. In combo with Roon, I find navigation pretty easy using search function. Sound is pretty good, streamed through Sonore Ultra Rendu into Sonore Ultra Digital into a Denafrips Pontus II via I2S over HDMI. I don't notice any bass bloat. Yes, there have been fruitless searches, and then there are the files that do come up, but with that dreaded red "not available" warning. But I have used Qobuz to add many albums to my library that I could never afford to buy, even if I could find them. My library has gone from about 2200 albums to over 5000 since joining Qobuz. The seamless integration of my server with Roon and Qobuz is fantastic.
I don't have anything special in terms of signal transfer, but I did move from WiFi to Ethernet when I got the Sonic Orbiter bundle from Small Green Computer. So far, no dropouts at any resolution, only a rare, slight click or pop, like from an LP. I am talking like once a week or so.
But, as they say, YMMV.
