I'd say Playboy because that's actually where I first discovered Chuck Palahniuk's "Guts" and became a huge fan of his... but all are fairly irrelevant now. I dont remember the last time I really cared to pick up any of them.

Haven't looked at any of them in many years. But here's how I'd describe them from those days.

Playboy was the classier older sib, more understated. Penthouse was the self-absorbed younger sib, more overstated. Playboy is the one you wanted to talk to, and Penthouse was the one you wanted to party with.

Hustler was the pervy uncle that no one wanted to admit being entertained by.

I only read them for the articles....honest.
