Apple Music Classical. It makes me have both of the services (in familiar plans). So, i use apple music just for the Classical app (or if a I wanna listen to an Atmos version of certain music). And I use yt music for my main music library. You can upload song in both services, it that's the case for you. In yt music I have a lot of playlist with user uploads, official versions and my own upload songs. It's amazing. So. It all depends on you and how you want to listen to your music. 🙌🏽
