I assume the options will be TuneIn, Deezer and Spotify as native clients. I've not heard them doing a deal with Apple for Apple Music. However, you'll get Apple TV+ through WebOS.

Deezer is interesting if you have a multiroom system: it’s the only service allowing to play different songs in different rooms with the same account.

spotify is interesting if you’re alone and you drive a Tesla (only streaming service available in Tesla cars)

Apple music is nice if you have a HomePod somewhere and don’t mind draining your phone’s battery wile using Airplay on your BV.

if your question is about quality, they’re all equivalent, but there is no high quality offering with Apple Music.

I’m not sure of what you mean by « supported across the products » but you can play in sync across almost all current B&O products with Deezer (integrated or with Google cast), and Spotify (Google cast or airplay, Spotify connect not allowing multiroom) or Apple Music (AirPlay)
