I haven't taken the 16 personalities thing. Probably will when I get home. For the enneagram I am a 5w6, and found that to be very accurate when I read the description. I recommend not reading about the types before taking the test.

Enneagram

I took the classical one first since it is the more accurate. Then I took the other one which gave my instinctual variant (the 6 wing). The first one shows you how strongly percentage-wise you are aligned to each type, which was interesting.
