Never much cared for craftsman stuff. Most of my hand tools are Mastercraft Maximum (from Canadian Tire), and seem to hold up pretty well. Absolutely no question with regards to replacement, at least at the store I go to. If it's a ratchet, they ask if I want them to rebuild it (which usually only takes a few minutes) or a new one. I usually get them rebuilt.
I break stuff from being stupid all the time, mainly because I know that they don't care how I broke it, they just replace it.
The only stuff I've really had quality complaints from Mastercraft are Torx heads in 3/8 drive. They break on the first use, every time. They still replace them, but the replacements don't seem to last either.
Bought some Stanley hand tools, not impressed. Got a full 1/4, 3/8 and 1/2 drive set from them. Right off the bat the 3/8 and 1/2 ratchets didn't work. Got replacements but in that case I had to wait for shipping, ticked me off a bit. Also the sockets have printed numbers on them (or laser etched, whatever they call it) that wears off very quickly, making it hard to tell what size you've got. I have a bunch of older Stanley screwdrivers and stuff that are great, but it seems the quality has gone downhill quite a bit. I wouldn't recommend.
Snap on is great but way overpriced. I have some older stuff but never bought new. $100+ for a ratchet is ridiculous, even if it is the best.
