Ended my Qobuz subscription

I went the other way - I cancelled Tidal and settled (for now) for a year's subscription with Qobuz. I thought MQA was pretty good, but the high-res flac files (92 kHz, 24 bit) at Qobuz are just as good IMO.

Me, too. I did find Tidal's library to be slightly bigger but I'd *much* rather have 24 bit PCM than MQA (the main reason I switched). Meanwhile, it appears than the Qobuz library is expanding.

Qobuz has 96/24 and Tidal has MQA, 94/24 is slightly bigger file than MQA. At home set up, Qobuz SQ is better than Tidal. On the road, depend on cellular reception.

I'm  a big fan of folk, americana, and the like. Do I assume correctly that neither Tidal nor Qobuz would have a catalog to satisfy my musical
tastes?

You can find plenty of folk/Americana on Tidal.  I think that you can get a 30 day free trial to find out if they have what you want.

I don’t remember all the many examples of an album I searched in both Qobuz and Tidal. I read a lot of jazz magazines including Jazz Times, DownBeat, Jazziz and search for artists as I discover them in writing. Tidal, as pointed out before has more. I saw no reason to keep Qobuz. 
I don’t do play lists except my own. I ignore the hype and suggestions. 
I agree with kacommes about the weak search in Tidal. Any misspelling and you don’t find it. It is definitely not comparable to a simple google, bing, or Duck Duck search that will offer variations. Also if you search an artist by name they may not show the albums with other variations, eg  “trio”, or live, or with xxx.
