I'm going to be honest, I really like the 12V Max DeWalt tools, but I fell in love with Bosch's newly redesigned drill (PS31-2A) and impact (PS41-2A). They are both so small, and so powerful. The 3/8 drill is by far the smallest 12V Lithium Ion drill out there that I've seen.
DeWalt hit a home run with ergonomics. I think Bosch for my hand was a 2nd but I chose Bosch because of it's size and build quality.
Anyway, my 2 cents.
