Qobuz.
Enough said.
But if you want more said, it is better quality audio (especially useful if you're into hifi and/or headphones. You can also buy audio tracks directly from their store too. Oh and if you also like classical nothing beats it.
Full disclosure, I also use YT Music as I pay for YouTube Premium and it comes with and it has a bigger range but the quality is only about as good as Spotify. It's fine...but qobuz tracks have more "feeling". It's weird. Minimum quality is CD level but,.and especially for classical, higher dynamic range makes tracks just more. If you're listening on quality open-backed headphones with a wide soundstage, your ears will love it.
