Craftsman have an unconditional lifetime guarantee too. Got a 3/8" drive for my b-dy x-number of years ago, had no receipt when it stripped out, took it in and no questions asked walked out with a new "refurbished" one in a matter of minutes.
Most tool makers these days have lifetime guarantees. Its more of a matter of the store which honors the guarantee will being around when the time for a warranty claim comes up. Sears has been around since the early 1900s, if not longer (just guessing here). Home Depot has only been a player for maybe 20 years, and with home improvement stores coming and going these days, its tough to say if they will stand the test of time.
My first choice would be Snap-on, but finding a salesman to buy from and in the case of a warranty claim, vs. going to a Sears store which rarely moves and has solid hours. Unless you are a mechanic in which case you have a salesman stop by your shop regularly.
All of that being said, I have never owned anything but Craftsman and with the exception of the one warranty claim above have never had a single problem.
