I've always used 'mid-range' stuff, even at work (I'm a tool maker, not a mechanic). I've cracked exactly one socket in 50 years. I've never had a problem with (older) Craftsman sockets and wrenches. I recently bought a couple sets of Gearwrench sockets, and the ratchets are sooo smooth. My old Craftsman ones feel like they have rocks in them.
Certain things I only buy good stuff. In my trade, we use Allen wrenches hard all day long. Wera Hex-Plus hold up better than any others, and I've used a lot of them. Cheap screwdrivers just ****. I also like pro-level power tools for the added power, function, and life-span.
I'm 66, recently retired, and living on SS. I really don't need any more tools (did I just actually say that?!?). I'm starting to scale back on projects, and some things, like climbing on the roof I just don't do any more. At this point, I'd like to thin out my tools some, and maybe replace a few sketchy tools with better ones. That's why I bought the GW sets; my old sets were a mish-mash of mongrels, and I like having a matched set in a handy carrying case.
