I?ve always ran Milwaukee. I?ve only had one issue with my impact driver that they covered under warranty. After using it, it would make a high pitch whine for 10-15 seconds. It never drained the battery or caused performance issues, just made a weird noise. I recently picked up a Milwaukee cordless impact and can say that were not joking when they said 1400lb/ft of ?nut busting? torque. Project farm provides some real world, un-biased information and IIRC, Milwaukee has always taken the cake. Either way, I don?t think you can wrong with DeWalt or Milwaukee.
