personally i use dewalt heavily. They bought the milwaukee fuels at my other job. They suck imho. My dewalt 20v is better in so many aspects.

The 18v dewalt stuff I have no interest in however. Gotta buy the good 20v stuff. They make cheap 20v drills/etc too but obviously like anything ya get what you pay for. Lean toward the higher end dewalt stuff and you shouldn't be disappoint.
