Moser vs Strange

I ordered a set of Mosers and when I got em one was threaded for studs and one wasnt, called em up and they said that that would be impossible as they have strict quality control. I did not have the time to send them back so I went and bought a $40 tap and threaded it myself. I ran them for about 6 years and never broke one but will not deal with them again so therfore I vote for Strange as I have some of those also.
