Maybe there are two best kinds of cookie sheet — one that you can cut things on, and one that just turns out awesome cookies?

Editor: Emily, I have a pretty strong preference for commercial-quality half-sheet pans. (Ina Garten says that she thinks are a really overlooked and helpful basic, too.)
These are heavy-duty, and they won't warp at all! They aren't nonstick, but I never have problems with them; just grease them or use parchment. They conduct heat evenly without the air-baking gimmick. You can find these at any restaurant supply shop and on Amazon. They aren't just for cookie-baking, too; you can use them for everything from roasting pork chops to toasting nuts to baking a loaf of bread.
Readers, what are your favorite cookie sheets?
