best friendships/sisterhood?

Which sororities have a strong sisterhood? So many topics on this board tend to rate the best sororities based on which high school you attended. That makes a great sorority??? I am very fortunate to have attended one of those desirable high schools and I loved every minute of it, but honestly why is that a big deal?? I loved my high school and my friends, but I thought the whole point of college was to make a new start and meet new friends. To be honest, many of my friends from high school look down on the fact that I am going to A&M at all...they don't consider it prestigious enough but I don't care - I am thrilled to be an AGGIE! I am excited about the upcoming Recruitment, but I honestly don't want to join a sorority that is made up of the same cliques from high school. I also don't want to join a sorority because of how much money each girl's family has...who cares. Most of the girls from my high school are in the same two sororities at A&M, and unfortunately they seem to still be "stuck" in high school - they haven't moved on or branched out with new friends. I want to join a sorority where the girls really like each other, enjoy hanging out together, etc. So my question is which sororities really have a great sisterhood? I know with so many girls in a chapter everyone is not going to get along, but who has the reputation for really liking each other? Thanks and Gig 'em!
