I would imagine they're identical (with the exception of the licensing as one is standalone and the other part of a suite). Bad enough having 2 versions (Max and Max Design) as it is, to have different versions based on the all the possible suite combinations as well would be a nightmare (and pretty pointless).
Someone from AD would have to confirm that, of course, I have no "inside knowledge".
