I don't have any experience with either of those drills, however I do have several different types. I find myself using this one the most:
Makita 12-Volt Max Lithium-Ion Cordless 3/8 in. Driver-Drill Kit-FD02W at The Home Depot
It's really lightweight, comes with an extra battery and charges faster than I can run out the new battery. This is mostly for electronics though. There is an LED that shines forward while you are using it too. Comes in really handy.
