LII-IEI; 5w4 ---> 5 (LII)-w-(IEI) 4.
Socionics b/c of the inter-type stuff... However, the more I learn about the Enneagram, the more I find it describes my motivations well.

MBTT is way too simplistic a system to capture something as byzantine as personality, (most ppl's anyway... There are some personalities I could describe with a word... Usually four-letter...)
Me, enneagram; my relationships, socionics.

From what I've heard, it's rare for an IEE to be 6w5. So I don't think personality can be solved by using any of the existing systems alone.
