I recall that the Fluffy All was simply not concentrated like All with the 3Bs. Both were low sudsing though.
Regarding the personalities that advertised Burst, I don't recall Joan Lake in the NY area. The Burst commercials in our area featured Susan Strong lining the bottom of a trash pail with a dishtowel to show how clean Burst would get that disgusting stained rag- she did a lot of household type commercials.
