Damn, we need to make this a stickey.
Craftsman, Allen, Kobalt(Lowes), KD, NAPA tools, Gearwrench, Armstrong, Matco, are all brands of Danaher Tool Company.
Essentially Craftsman, Allen, Kobalt, KD and some NAPA tools are all the same tool. With some cosmetic differences in each brand to make them "look" like they are different tools. A Craftsman rised panel 1/2'' ratchet is the same a Allen 1/2" just the Allen has a different shape handle and chrome finish, same goes for Kobalt. Allen socket are identical to Craftsman and etc.
Gearwrench is Danaher's Asian line of tools. But they are good quality, IMO.
Armstrong is Danaher's industrial line, which is of higher quality.
Matco is Danahers pro line, highest quality. However some things like impact sockets are pretty much the same as Craftsman's.
With in these 5 or 6 brands Danaher shares alot of the same design and technology( such as x-beam and pinless swivel impacts).
Anywho to answer your question Armstrong is better but Allen tool aren't bad either. If you get that Allen RHFT long handle ratchet at Menards, lots of people on here really like the Craftsman version of that ratchet.
