Bf as in best friend

This is pretty accurate

Call ADPi a powerhouse -- their good chapters in the SEC are really good, but their bad chapters are really bad.

AOPi is more consistent IMO. They're in the top tier only at UGA and Tennessee, but they're upper middle/solid middle everywhere in the SEC except Kentucky and Ole Miss (and the chapter there would probably be middle at another school).

Every strong Southern sorority has at least a few weak chapters almost. DDD and XO are maybe the only exceptions. KD would be too before A&M and Mizzou joined the SEC. Kappa is top at about 7 SEC schools plus all of the Big 12 Texas schools, and at least several ACC schools, so I'd call them a Southern powerhouse even though they are pretty middling at LSU and Ole Miss and lower at South Carolina and Auburn. I'd call KD and Phi Mu Southern powerhouses based on SEC/ACC strength, but in Texas KD like ADPi is lower middle at the only relevant Greek schools they are present at, and Phi Mu isn't even at any of the big Greek schools in a major Southern State. Notice I called ADPi a Southern powerhouse, not just specifically SEC. They have several top tier chapters at relevant Greek schools all over the South. Generally the sororities I'd consider Southern powerhouses are KD, DDD, XO and Kappa followed by Phi Mu, ADPi and maybe Zeta. Zeta aren't necessarily top at a ton of big Southern schools outside Florida and Texas, but with a few exceptions like LSU they tend to have a consistent enough strong middle tier presence with fewer lower tier chapters than Kappa, ADPi, KD or Phi Mu to deserve a mention. KD, DDD and XO are of course the clear winners in the SEC, but there's room for a few more "Southern powerhouses". AOPi is probably pretty similar to ADPi in SEC strength alone, but are virtually nonexistent in a lot of the South, so I don't see how they get preference.

SSS only has one (struggling) SEC chapter, and is barely present at D1 schools? ADPi, AOPi, AXO, AXiD, SK, Gamma Phi and probably even SDT have a better shot.

You're basically right, but on the other hand Tri Sigma does have four chapters in Louisiana.

Has a terrible track record in the SEC -- all but one of their chapters are closed, and the one remaining (Auburn) is at the bottom.
