Big Five vs 16-type
The Big Five is what personality science actually settled on: five continuous, well-replicated dimensions with no type boxes at all. The 16-type system is older, more memorable, and more shareable, at the cost of cutting continuous traits into binary letters. The awkward secret is that they largely measure the same territory; four of the five Big Five traits map onto the four dichotomies.

If you want the most defensible measurement, the Big Five wins and it is not close. If you want a language people remember and identify with, the letters win. Our 16-type test splits the difference: letters on the outside, honest percentages underneath, and a coin-flip letter gets called a coin flip.
