Quick story/experience with DeWalt. Bought a 18volt kit in 2006, included sawzall, circular saw, grinder, impact, hammer drill, flash light, small cordless vac. When I had a job where I used this stuff daily drilled thousands of holes in 3/16 steel angle, drove in 1000s of tapered semi self tappers, 1000s of 1/2"+ carriage bolts, and lags with an impact Almost 3 yrs after owning, the drill and impact were completely trashed, took it to the DeWalt factory store they completely rebuilt both free of charge. Still have one or two original nicad batteries that hold a charge (barely) and aren't really usable. In 2006 anyway DeWalt used smarter chargers than Milwaukee. Over more recent yrs went with newer 20volt stuff none of it has given me any problems and a lot of there bare tools can be bought at reasonable prices
For me anyway DeWalt is worth the extra cost mostly for the ease of mind and fact if I need it to do something requiring my DeWalt tools it's going to work.
