I'm pretty sure I'm 6w5. And sp/sx variants seem to fit me best in terms of descriptions I have come across.
However, I have also sometimes scored high on 1, 4, and 9. And even 2, I think. I think the 2 has to do with circumstances and the fact that (especially for a single person without a family of my own) I feel a strong degree of responsibility for a significant number of people in my life. 2 really does not fit me, though. Some might think that 5 fits me, if they see my more introverted/intellectual side, but it really does not. It totally fits my mom (INTJ) and I know where she is fundamentally different from me.
9 and 1 both fit in many respects, especially 9 - I think 1 is more that I strongly identify with a few aspects, but only a few. I am still not 100% sure that I'm not 9w1. I think 4 only really fits insofar that it's a common INFJ enneatype and I relate to the artistic side - not to very much else, though. It would have fit me much better when I was in my teens.
I don't identify at all, or very little, with 3 or 8. And maybe only a tiny bit more with 7.
