Just join one that you like best. Talk to them, see which one you are most comfortable with.

Don't do it for the reputation or who is "top" house. Every fraternity has their own traditions and secrets.

If you're looking for a way to get into secret societies, that solely depends on the people in the fraternity. There is no secret links between certain fraternities and secret societies. I also want to point out that even though a fraternity has roots with certain secret societies it does not mean the actives are part of the society. It could be just part of the fraternity history.
