Real men eat Porterhouse. Prime Rib, despite the theoretical quality, is the "cheap part of the good part" of the cow.
Filet Mignon is awesome, but it's usually so tiny that after eating it you feel... dainty. That's why the Porterhouse (T-Bone for you plebes) is my favorite: a little of the Mignon, a big chunk of (mostly) lean tastyness that's just as good as a Prime Rib.
P.S. I forgot to mention that I'm a bit lucky when it comes to good steaks; the entire Northern Nevada area has been heavily populated by the Basque and their decendants, and no other culture I've met quite knows how to cook meat of any type as excellently as the Basque. As a bonus, the Basque are traditionally sheepherders and ranchers, so we have no shortage of beef, lamb, pork, and whatever else around here. Prices are cheap, especially if you go to a Basque restaurant. For about $35 I can get an inch-thick 30oz Porterhouse at Biltoki's in Elko, and keep in mind that includes soup, sides,. salad, more sides, fries, still more, a big jug of purple death (wine) and desert.
In short, come to Northern Nevada if you like outstanding quality beef that's reasonably priced.
