I switched from Yt Music to Tidal because of audio quality and it's audible. But the difference between Spotify highest quality and Tidal is truly minimal. I did the tests and I couldn't hear it. I kinda prefer the UI and generally like supporting market alternatives if they're good and if they pay artists better, then that's even better. I don't listen to podcasts either, so those are my personal reasons for choosing Tidal over Spotify.

I have never really used Spotify, but my partner insists that the recommendations on Tidal are actually better. I also think the recommendations are great, but work best for genres that Tidal is strong at. Of the genres I listen to, I've had really good experiences with the genres hip hop, rap, lofi, misc. electronic music, western pop, and less good experiences with classical music, soundtracks and more niche genres like J-Pop, African Pop and random trash (on Spotify, our we used to like to prank our friends by adding stuff like gangster's paradise kids bop version or "female orgasm sounds" to their playlists. I haven't really found prank-worthy stuff on Tidal yet).

So it's really a personal decision and tbh, I think Spotify is the better choice for most people.
