I weigh in on the DeWalt side, and have had a 12 volt for several years (two batteries) and a 14.4 volt for two years (two batteries). I find I can work steady, with a battery lasting more than the hour or less that it takes to recharge the second battery. Never waiting for a charged battery. I don't leave batteries in the charger, but store them when they are charged. They have always been ready to go when needed. I hired a carpenter (with a portable Makita) to help me put steel siding on my shed, and he laughed at me when I brought out my DeWalt to screw in the screws. He said to use his Milwaukee 110 v screw gun, as the cordless wouldn't last. He was quite impressed when it kept up with the screws as fast as he could get the next panels cut. The last time I saw him he had a DeWalt. I need two as I keep them at two different work sites. I expect the DeWalt is not the only kid on the block, but I wouldn't buy anything else.
