I have used both and for light /med duty I use the milwaukee cus of the long bits they have but for heavy duty I definitely go with the dewalt impacts.
Well I would like to buy more tools but T.I.A has broke my check book!!!! Lol!!! I'm hopeing to get the new Mac set powered by dewalt batteries for the shop ,dewalt brushless nailer and overall just expand my dewalt 20v line :}
I too baby my dewalts I try to keep them bright yellow but when ur workin with other people and your both using only your tools they don't give a crap aboutem!!!! Lol like Tyler said if u take care of them they will take care of u.
