I work consulting in the service and body shops of car dealerships, back with the mechanics at scores of different stores. Milwaukee is the standard that I see professional mechanics (who buy their own tools) using most of the time now, and the high end tool trucks are also selling Milwaukee. There are plenty of snap on cordless impacts and ratchet users, but those guys all seem interested in the Milwaukee product too since it costs half as much. I see the occasional Makita, Dewalt, Bosch, or Ryobi, probably 10% of the time between all those brands. Milwaukee may have some minor issues, but I don’t hear many complaints and warranty service is good. Milwaukee is doing a great job of targeting the trades with specialty tools (like extended ratchets) that the other homeowner brands aren’t doing.
All my personal stuff, and there is a lot of it, is Milwaukee. I buy the Fuel brushless tools most of the time, but certain tools like my M12 screwdriver, are the brushed models. Dewalt does make a 8v cordless clutched gyro screwdriver I have that’s a lifesaver working on RC cars.
