Had the best perks without actually being in one. One of the largest ones, at one of the largest campuses in the world, courted me because (humble? brag . . . my GPA)
They had a separate honors lodge, completely separate from the massive animal-style house, and I was guaranteed acceptance, lodging there, and practically no hazing during hell week.
I never went through with it, but my best friend, who was not courted for his GPA, joined. I could walk into the main house at any hour and I was accepted. You just never hit on a woman at any of their parties, and I was friend of one of the senior members.
