which sorority is the best out of these?

Bias opinion: Phi Mu, my sister is a Phi Mu and she loves it. They keep getting better each semester and are becoming top tier on campus

Non-bias opinion: Any one of these are great sororities, rush all of them and see what you like

Your best bet is to go into rush with an open mind, and go with the flow. Just because you hear that ABC sorority is the very best on campus, doesn't mean that it would be the best place for you. On top of that, you might not get asked back and then where are you? You either pick yourself up and pick another favorite from the ones that did ask you back, or you let your disappointment get the best of you, and drop out and watch all your friends and dorm mates have fun with their new sorority sisters because they stuck with it. Meet the girls during rush and then form your own opinions based on how you feel and on your own experiences.

to FSU DC, phi mu is NO where near top tier at FSU... when I rushed I did not like them, but I think I got a bad pairing because a lot of friends kept them around for a while. I dont know anyone in phi mu but they seem to be nice girls. Go in as open minded as possible, and don't get down on yourself when you get dropped from houses you wanted. On the 3rd round I got dropped from my favorite 3 houses and I almost quit, but I stuck with it and ended up prefing 3 top sororities and am in love with my choice. Best of luck!

Those are not generally recognized as very desirable. Why are those the ones you've chosen in advance? Btw, that's not a very smart way to choose a house...
