The Gear Wrench stuff is awesome. I have quite a few of their tools. I love the reversible ratcheting set.
As for other stuff, my toolbox is mostly Craftsman, some Kobalt, and even some Stanley.
My specialty tools are a mash of assorted brands.
I've only broken a few Craftsman items. Honestly, its nice to be able to easily get a replacement at the nearest Sears than try and track down a truck. A good friend of mine is a professional mechanic, and agrees with me. At work, he has the top dollar tools, but for anything else, you can buy 2-3 Craftsman for 1 of the others. Yes, the top dollar tools are less likely to break, but if you only have a certain amount of money to spend, its cheaper to buy something like Craftsman, and have spares. Especially if you aren't doing this for a living, and have regular access to their tool trucks.
