Blue Point appears to be above the "common" stuff (which is itself above the junk), but below the super-mega brands like Snap-On, Mac, etc. Is that about right?
Much of Blue Point rivals Mac, Matco, and Cornwall. EVERYTHING else is a cut below those, with the exception of a couple of specialty brands that are not commonly available, especially in the States. Craftsman is the worst of the bunch these days unless one gets their pro line, which is, in many cases similar to a Blue Point, Mac or Matco. Snap On is a cut above all of them. Price point is mid-way. Know that many automobile engineers design their vehicles around Snap On tool sizes. That means that a Snap On tool will fit and work, but a rival brand may not. For much of mechanics work, it is whatever fits, but there are some really trickly spots where nothing seems to fit at all (including Blue Point) -- it is there that the Snap On will fit. I found that to be the case one day during a car show when a person had to change out a Boyd's custom wheel. No socket would fit the lug and the machined hole for it except a particular Snap On brand. They actually called me (with my tool truck) to the show to figure out what would work. I've seen similar in dealerships of every brand.
