advice on these frats

I am going to Rutgers this Fall 2014 as a transfer, I don't really know much about the greek life at Rutgers but am very interested to learn and join a frat this upcoming Fall. Maybe you guys can help me since it seems most people here have some knowledge/experience on these frats. Some of the frats so far that seems to interest me are…

-Alpha Sigma Phi
-Delta Chi
-Sigma Chi
-Theta Delta Chi
(these are not in order in any way)

I have looked at their websites but this website says different things than their websites so it confuses and makes it harder for me. I want to join one that has a strong brotherhood where they actually care for each other even after college. They don't have to be popular but at least making their way up there. Have a decent or good philanthropy, I would love to help out in any way I could so I'm looking for one who actually cares about their philanthropy also. I am also looking for one that has benefits after graduation. Maybe throw some decent parties there and then to enjoy and relieve stress (CS Major). Can you guys tell me if any these aspects I mentioned connect with the frats I mentioned on top or give me a solid true summary of what they are about. Feel free to mention if any of them haze or who to watch out for when it comes to hazing.
