HUZZAH Your thread shall be Revived! Really the only difference is 3 and 4. Identity vs Image. 783 seem to be triple aggressive and triple expanisve, and 784 triple freedom, and triple creative. Those are the only key differences I can think of.
I know for me personally I kind of stuck between the 2 types because I can't decide between 3w4, or 4w3 for my image.
