I think the cognitive function model is fine and useful, which is why Dr. John Beebe's model is so appealing.

My main issue with Meyers-Briggs is the use of a questionnaire to type people - I'm an ESFP, but every time I've taken an MBTI test I've gotten back INTJ or ISTP. I never felt that either of those were completely accurate, or that I was an introvert. It's far, far more accurate to type people based on their preferred styles of interaction and thinking (e.g., as an ESFP I have an informative, initiating, movement-based interaction style and I think in concrete, pragmatic, interest-based terms).
