Qobuz vs. Tidal

I have found that Qobuz has a much larger classical library.  Tidal has a better interface.  Spotify has great algorithms for passive listening.  I keep all three and listen almost constantly. 

Qobuz is preferable due to larger hi-res catalog but does not offer as many titles as Tidal. Many songs in my playlists cant be found on Qobuz. The Tidal Android app is also superior (for on the go listening). So....I compromise and subscribe to both.

I had a very strange experience when comparing Qobuz to Tidal a couple of years ago, when I was trying to decide which service had the best sound quality.  I pulled up "Jack of Speed" from Steely Dan's "Two Against Nature" album. 

There is a prominent trombone phrase throughout the song which sits fairly upfront in the mix on the original CD and on Tidal.  When hearing it on Qobuz, it sat much lower in the mix. It was as if someone did a re-mix (not just a re-master), and really lowered that individual track.  I don't think it had been re-released at that time, so it left me scratching my head and thinking WTF.  That made my mind up to go with Tidal.  

Which one of the two has a larger metal / alt rock library ? I can find almost all I want on Spotify but the quality is not that good.

Anyone using QoBuz or Tidal with a Bluesound Node 2i?  

Just curious because that’s what I’m using with an Audio-gd NFS-1C DAC.  I have Spotify Premium, which to my ears, doesn’t sound too bad at all.  Wondering how much better QoBuz will sound?  Thanks 🙏
