Aphi basically picks who's gonna be in their pledge class that year by their Instagrams and is very competitive/you must be hot, theta is new and taking lots of girls, and having a legacy at chi o could help. However, they are also in the top 3/are more selective. They're also known for being the most sloppy.

Yes, being a legacy will help you with axo. I have a lot of friends in that sorority and they are really fun, cool and real girls. aphi has a rep for being pretty fake and not a great sisterhood but do have some nice girls. Theta got a great group of girls and is coming on strong.
Just go through the rush process. You'll most likely get a bid from axo and probably some others. Go with the one you like best and would feel most at home in.
