In the major USA wrenchbrands; Snap-on (and the older Blue Point), MAC, Matco, Proto, S-K, Williams, Wright, et al, there aren't any deal-breaking faults. As has been previously stated, they'll all do the job for you, so just buy the best deal on a complete used set.
The next step down, Craftsman, depending on vintage, might have made by Moore Drop Forge, Stanley, Easco or New Britain. The most recent supplier is the Danaher Corp who bought Easco and then branded the same Craftsman wrenches NAPA, Easco, they'll also do anything the non-professional user needs done. They're just not quite as pretty.
Same for sockets; at one time, Danaher made all the sockets for Craftsman, Easco, Matco, Proto, Allen, NAPA, and K-D. There is no difference between any of these sockets, in any way, except for the name.
Bottom line - they're all good enough to be equal to the talent most of us are putting into the work.
You didn't ask, but IMHO, the biggest difference is in ratchets. That's were there are enough differences to be worth an argument and where your money buys something you can see and feel.
