When I was a young lad, I worked in a motorcycle shop as a mechanic. Used lots of phillips, hex and torx bits in impact driver. I had then, lots of craftsman tool, I was in college, was all I could afford. Whenever I had a tough screw or bolt to get out, I borrowed the other guys Snap on impact driver, one smack, problem solved. SO...... bought my own Snap-on driver, used it with craftsman bits. Those bits might have lasted two weeks max each, I was constantly going to Sears and getting them replaced. Yeah, it was free, but it was time out of my day every couple weeks, to exchange a handful of bits, not just one or two. I had to have spares in order to use Craftsman bits, they didn't last. Finally broke down and bought the sets of Snap-On bits. Never broke one over the next two years.
Same deals with their screwdrivers and wrenches, if you round it off with your Sears product, you can usually put your Snap-On on it, and get it loose. On the large turbines I work on now, with 2 and 3 inch diameter bolts and nuts, Snap-On is usually the preferred socket, they just don't break. When you have a dozen guys costing $100 an hour, you can't wait on a broken socket to get replaced.
Guys that make their living with tools, don't buy them at the hardware store. I keep a cheap set of torx screwdrivers at the ranch for working scopes and mounts when visitors inevitably have issues/ swap scopes etc. I hate it when they snap off, or twist off, but don't want to leave a nice set of Snap=On unattended when I'm not there, they won't be there when I get back. No one steals the cheap one though... imagine that.
