I was an S1 app user as well, I've never even used or heard of S2 until the recent drama. I think it's worth highlighting that "Play X in Room Y" mandates defined rooms, and if you are in any kind of living situation in which this is not the case, Sonos is not right for you.
As a long time apartment/condo dweller, Sonos basically can't do what I'm looking for.
