Personally? I find Youtube/YTMusic scarily accurate at maintaining "coherency" between tracks. I could listen to a 1 hour (human made) mix and I won't realize when the mix ends and the algo picks up. Spotify (for me) mixes upbeat tracks onto slow songs and mixes instrumental tracks with vocals and whatnot. Youtube rarely misses for me.
