The differences between Tidal and Spotify are minute enough to where you're not likely to notice if you're actually listening to the music and not actively trying to dissect tiny details of it. I notice a -very- small difference between the two but I switched over to Tidal just because I was bored of the stuff Spotify kept recommending me year after year and I wanted to give hifi a shot. It's not night and day and who knows if I actually hear it myself, but here I am. They're the same price anyway so I don't care.
