I'll give you this: I don't have a playbar, but I do have 2x Play:1 and as of the last few months it has been atrocious. Consistently I (and many, many others) have been unable to browse or play anything from Apple Music. For nearly a month we were unable to browse ANY playlists on Apple Music (Favorites Mix, Chill Mix, etc.). Nothing that was created by Apple would show up. A fix arrived for that about 3 days ago, but as of right now all we're getting is "unable to browse music".
So, at least for me, I regret purchasing the Sonos and wouldn't look towards another of their products.
