This is great to see. I ended up moving to Tidal from Spotify, and even though there are some nice to have features missing from Tidal (an equivilant to spotify's sync between devices/speakers as well as a better Android Auto experience), it's a far superior experience.
Quobuz is also on my radar, but they've traditionally lacked in the music catalog space. I need to give them a try again now that it's been a few years.
That said, Tidal barely has Linux clients and I don't think I've seen much movement for Quobuz on Linux, unless I've just missed it.
