So, from what we know, the only advantage the EMS has over the MS is that the user does not turn blind... But, Itachi's MS regenerate, so the EMS has nothing in advantage... So, do you think that Itachi has EMS by Edo Tensei?
I think that without the blindness and the fact that non of the Edo's seem to get tired or lose chakra he's about on par with EMS with his Mangekyo. I think that its pretty much the same thing at this point but there bound to be a loop hole where EMS is somehow still superior.
