Music streaming

Qobuz for sound quality, but sometimes they don't carry an artist's best work. For example, Tom Russell Band, Poor Man's Dream album. All you get are shabby, feel-good live recordings of some cuts from that record. They also don't have the Poco album Cantamos. Two years ago they didn't have the Amplified Heart album by Everything But the Girl, nor the single We Walk the Same Line from that album. Now they do, but it took a while. Though they did impress me with Brother Wiley's Murder the Mystery album, which I strongly recommend, especially for the rock 'n roll cover of Cohen's First We Take Manhattan. And they had another rarity, Air Loom, Seeds, for the single Forgive This Town. Qobuz is missing some of the best Albinoni and Telemann as well.
That said, Apple has the more comprehensive library. MQA put me off Tidal forever, and Spotify doesn't seem to take SQ seriously.

I have Qobuz and Tidal and they both sound excellent.  I have both because sometimes I will play something on one platform that is not available on the other.  

I prefer Qobuz but Tidal has great exclusive live content with artists.  

Been using Tidal for years. Love it. I listen to everything from rock to opera. Music library 970 and counting. 

Many Tidal vs Qobuz debates here...but with your streamer, you should get the one that works best for you...

I had subscriptions to Tidal and Qobuz together for about 4 months. I settled on Qobuz.  I preferred its library format better and thought its SQ marginally better.
