NewBee,
You didn't mention why you chose Iota as a close second.
I would be an Alpha or an Iota. My reasons for chosing Alpha Phi Alpha are pretty much the same as others. Besides, I got mad love for the phirst pham!
I would also consider Iota because they are the first greeks that I met when I was an undergrad. All of them that I ever met from every school (except one) were perfect gentlemen. I like how tight they seem; their brotherhood is very welcoming.
