I have Tidal and Qobuz. I listen to Qobuz more, turning to Tidal when I can't find something on Qobuz or if I want to listen to one of Tidal's "My Mix" playlists (they are usually good). I have one DAC with MQA and listen mostly with a DAC with no MQA. It sounds as good, if not better on the DAC with no MQA, mostly because it's a better DAC and a more resolving system.
You can hear differences between MQA and no MQA. Are they better? Worse? It's subjective. Will you hear a track that isn't MQA and say to yourself "that sounds awful!". I doubt it. Will you jump out of your seat because the MQA version is so much better? I doubt it. More depends on how it was recorded, mastered, your system, etc. than whether it is MQA or not.
