Yes, of course, the notation that is used is of paramount importance. Probably among the people you know the ones that are familiar with MBTI and don't know shit about socionics use the MBTI notation. I on the other hand use it because I am more comfortable with it, though I don't know as much about MBTI as I know about socionics. Which does not necessarily mean I know much.
As far as my superficial stereotypical behavioral cues ... you could be right. Though I think you threw in the adjective "stereotypical" trying to imply that it is a bad thing while according to my understanding socionics is mostly about stereotypes. I would not argue about what I wrote being superficial.
