No idea. Deezer is DRM free, has a deep catalogue, has a solid API, and provides high fidelity files. I have no use for other services. Personally I’d recommend them. As an example of a personal project I’ve built on their API: https://audile.app (a random album on every page load)

Unless you have an online service you won’t be able to keep this playlist in sync on another platform as I continue cultivating it. I do keep a backup of the playlist in the event Deezer disappears.
