Gotta disagree here. The Kobalt sockets I have used have been terrible quality and the fit was horrible. If we are talking about finish only then those other ones win, but to me it is more about the socket in use vs. how it looks.
Of all the time I have been on this forum, I have never once heard of someone complain about Craftsman sockets in use. Sure they have complained about poor chrome on some sockets (which I have heard complaints about many other brands just the same). Sure a few may have broken some sockets (Same goes for pretty much every other brand). I am not sure where you are getting that these sockets are lower quality than the others you mentioned (unless talking about chroming alone), because they surely are not. Price alone does not determine quality.
I agree, when used for their intended purpose, craftsman tools are of great quality and value. There are many other great brands out there as well. Look around, hold the sockets in your hands, talk to people who have used the set you're interested in, and in the end you will find a set that meets all of your needs.
