No clear winner. As tvad said, get a trial of each and decide for yourself. I’ll leave the whole MQA argument to the others.

^^^what @tvad said. 

My short and sweet description (or opinion if you wish) of Tidal vs Qobuz rests on a couple of things.

Tidal seems to be focused on a younger audience. Think hip-hop, pop, rap, etc. It's owned by Jay-Z. Qobuz seems to appeal to a more mature (OK older) audience, with an emphasis on classical, jazz, classic rock, etc.

Their catalogs overlap a lot, although I think Tidal has an overall larger selection.

Tidal uses MQA for "hi-res" files, which requires special software AND hardware to do the full "unfold" of the file (this they MQA capable DACs). Qobuz on the other hand simply provides a lot of high resolution files (mostly 24/96 to 24/192) that play through any DAC capable of playing hi-res files, which most can.

I keep Tidal because sometimes there are things that I want to listen to that aren't available on Qobuz, but that seems to happen less and less. If I was forced to only keep one, it would be Qobuz for sure.

+1 Big Greg's accurate description. I had used Tidal for several years but switched to Qobuz. I didn't feel like supporting JayZ and resented Tidal's "hi rez" MQA selections that forced you to buy decoding dacs. Qobuz sound quality is just peachy.
