That is a tough question to answer. Both companies produce quality tools. I have tools from each company. That said, I would go with the DeWalt drill. It gives you 200 more in rpm and has 20V of power.

I have a very old DeWalt hammer drill. I mean old. When the batteries run out I debate do I buy batteries or buy new drill. This drill is so good I buy batteries. I'm on my third set. The batteries last a long time. Anyway, I vote DeWalt.
