I started out with Spotify ... first free then paid. Later took trials of Tidal and Amazon HD simultaneously. At that time, Amazon HD (not to be confused with "basic" Amazon Music) offered a full 90-day trial. Not sure if that's standard or because of my Prime membership.
At any rate, based on the availability of truly hi-res recordings, and extensive jazz library, for me it's Amazon HD hands down. I found tracks there that I couldn't find anywhere else. Name an artist, and they got it. Again, that's been my experience. Cost is $12.99/month.
So I'd suggest getting the trials set up, switch back and forth, cancel subscription(s) on what you let go before auto-pay kicks in; and you're good to go! All the best.
Happy Listening,
Lewis
