The Super Deep likely (I am guessing) contains some alcohol, as well as probably more surfactant. I say this because the SD does not make any claims of no alcohol on the bottle and SVW does. Also, the SD is supposed to be used as the first stage of cleaning or for dirtier records followed by 2 sweeps of the SVW which does not need a rinse.
According to a number of people who have used both, the Art du Son leaves a sonic signature and the RRL does not. The Art also has to be mixed by the end user, with the quality of water obviously effecting the solution and the Art, after mixing, can go bad if not properly stored.
