This process is based on mutual selection but the only opinions you really need to take into account are your own. Don't base your decisions on what you've heard or what other people have said as that won't necessarily help you end up in a house where you feel most comfortable. Overall you are going to want to be choosing a house that you could see yourself (and the personality you have now) fitting into.
One last little did bit of advice that I didn't know about when I went through recruitment my freshman year is that it is ok to tell a sorority that you like them or that you are torn. Being genuine with your feelings is important while doing this but it can help the person in that sorority frame the conversation to help expose as much as they can about why they felt connected to their specific sorority with hopes of making the decision a bit clearer for you!
