Snap-On has dropped in quality in the last several years, especially in the performance of their air tools. Their prices have stayed up above the rest making them less desirable to do business with. I've had better luck with Mac and Matco. Matco used to be the "cheap" tool company but has really come a long way in the past few years.
I use a lot of Craftsman stuff at home, especially wood working tools. I can't afford 3 sets of professional grade tools so the home shop gets the cheaper stuff. If I have to, I'll haul home something from work if I need it on a personal project.
