I use Tidal at the moment, I was using Qobuz but often found that they didn't have the music I wanted. With a phone you also have to use a separate app called UAPP to ensure that music plays at the right sample rate through a DAC/amp and with decent volume. With Tidal you don't have to do that though you can if you prefer, Tidal can run in exclusive mode from the phone app. I enjoy using it quite a bit, they recommend stuff that I actually like rather than whatever is popular. They also show you how much of your subscription fee goes to artists and you can nominate an artist to receive it. I also use Bandcamp and Bleep to discover new stuff, I buy FLAC of my favorite albums from them.
