Both appear to have an actual dexos2 license so either one is going to be much like the other. As ollie notes buy the one that's least expensive and easiest to obtain.
I remember reading from BITOG a while back that the Specific line allows Motul to get their oil to the shelves faster for new approvals. Instead of making an oil and waiting for Mercedes, Porsche, BMW, and VW to all test and put their approvals on it, they just get the one approval they need and put it on the shelves.
