Since you do seem so much like me in several ways, I would say 4, 5 or 6. (Which I usually get in the vicinity of when I have taken the tests). Like 4w5, 5w4, or 5w6 or something.
9 would be if you're more Phlegmatic.
As for an exact estimate, I know the Enneagram in comparison to the APS temperaments, yet realize that outside of that, there's probably a lot about it that I don't know. Like I've never really gotten into the difference between the stacking orders, or those trifixes, and the degradations along the star image (I basically don't have anything to do with that star because it looks like some sort of mandala or something).
And thus I have not completely solidified a type for myself. If I had my way, I would say 6so8sp6sx or 4so8sp6sx (and the 4/6+8 averaging out to a virtual 5), but that's changing Enneagram into APS. So for you, again, it would look like in the vicinity of 4/5/6.
Have you tried Poriferan/Even's test (on here somewhere), which does give three different types somehow?
