top 3

Since Kappa mixes with phi psi, theta chi and aepi, that technically makes them a top 3 sorority solely based off of the frats that they party with. On the other hand, you have axo and skrappa who mix with Fiji and pike, which would technically put those two in the 4 and 5 slot. My question is, why do people think that axo and sigma kappa are better than kappa even though Kappa still is always with the top 3 frats? Kappa, phi and ddd have been interchangeable ever since theta got kicked off, I don't see a reason for that to suddenly change now.
