If I were the richest man on Earth I would have a bunch of Jim Cooke sandblasted pipes. Actually, scratch that, even the richest man on Earth probably couldn't get a collection of those.
If we're talking stock, out-of-the-box pipes, I'd take a bunch of Briarworks pipes (and sub-brands Neptune and Icarus). Those things are just about perfect.
That and Missouri Meerschaum, and probably Falcon pipes as soon as I get the chance to look over a few of those.
Missouri Meerschaum, while functionally perfect, are also ripe for customization, it's nice that collectors don't get mad at you for cutting them up.
I'm probably happiest with Cobs just for the entertainment value in the shop.
