*A was great, SkyTeam are pretty meh, although I thoroughly enjoyed the AF lounge in CDG recently, the Moet it doth floweth.
I guess it depends on where you live, where you fly and where you want to fly for your leisure. *A was perfect for me, LH and TK especially.
ST is very underwhelming, add in the byzantine nature of Lounge access and Fast Track and it's not a patch on *A.
