Corina,
I am going to chime in as I haven't posted on this thread in a while. I think you will find that sororities are more similar than they are different. All sororities have initiation vows which are different in word and ritual, but identical in spirt and ideal.
Virtually all sororities have badges, pledge pins, a philanthropy, cute symbols, cute merchandise that you can buy, etc.

However....some ways in which groups will differ (and this is important):
- which groups have collegiate chapters nearby?
- how many collegiate chapters are nearby?
- Are there alumnae nearby from those sororities, how many and are they willing to help support your new colony and eventual chapter?

These are not exciting reasons, but these are important factors to consider in selecting your National, and this is where the groups will differ in situation. Just something to help you see more clearly. Those national websites depicting cute, enthusiastic girls can make it hard to make up one's mind as to what sorority is right for you? So you need to look at the more practical and (dare I say it) boring factors (like alumnae support, etc).

Alumnae support is extremely important.
Alumnae support is extremely important.
Alumnae support is extremely important.
(So important, that I am writing it 3x)

Good luck!
