I'm not a pod people and I want to 'program' my own lists. I acquire tracks I want and run lists of 2,000 plus tracks that cover nearly a week at a time. It can be a month from the time I hear a song until it plays again. And only tracks I want, no ads, no talk, no interruptions.
My main playlist on Tidal is up to about 500 tracks so far. You have to pay basically around 10 bucks a month to get the ad-free tier on pretty much most of the services really.
Apple, Amazon and Tidal all offer higher bitrate files than Spotify. This does matter to a small percentage of people that do have the gear and ears to hear the difference. I like the HiFi quality of Tidal. When I put on certain tracks on my Beyers, Schiit Bifrost and Burson amp, it just sounds better.
A big differentiator as mentioned before, all the other services pay the artists significantly more.
The things that matter to people would be interface, suggestion algorithms, podcasts. I find Tidal and Spotify's interfaces to be pretty close with Spotify's a bit better, mostly in the phone app, though Tidal is no slouch. Spotify does have lots of podcasts, when I had it I tried to use it to listen to the MOTH and Radiolab but I just like the Podcast Republic app interface for podcasts much better so just went back to that. To each their own.
