I'm mostly with you, no diff - but some psychologists do make a distinction, both have no empathy, but the sociopath has spent much more time learning how to manipulate others and may have a desire to appear normal in order to get away with more stuff; whereas it may never have occurred to a purer psychopath that he or she should really try not to stick out so much, since s/he doesn't naturally see things (including him or herself) from anyone else's point of view. Historically, the term sociopath was first introduced as a replacement for "psychopath" since, for some reason, there seemed to be stigma attached to that term. Later introducing "Antisocial Personality" was tried as another attempt to duck the stigma. Somehow it didn't work, can't imagine why, and the terms have been at least slightly repurposed by at least some psychologists.
