Ryobi. I've had Makita, and they are fine until the batteries go bad. The replacement batteries are super expensive. I bought a couple of the Ryobi high capacity batteries with a fuel gauge for $49 for the pair. I have three drills, a drill-driver, a circular saw, a sawsall, a palm router, a halogen spotlight, an LED lantern, an incandescent work light, and an 8" chainsaw on a 8' pole that all use the same batteries. They all work great.
