Both excellent. User interfaces and auto playlist algorithms are very different. Qobuz interface and algorithms get me further out of my comfort zone and into newer recordings and artists. Tidal, less so. I use both to keep my listening fresh.
Tidal or Qobuz
Many say Qobuz sounds better than Tidal, not Jay.
