I'm currently running the Makita. Used it for fence last week, 3.5" lag screws for the main boards, 2" wood screws for the planks. The battery only lasted 20-30 minutes under that continuous hard use, but they were charged in 15, so I just kept rolling. Good torque, good speed. I like it, and Costco has the kit.

Last one was a Hitachi NiCd. Didn't take long for the batteries to stop holding a charge, but it served it's purpose for a while. Batteries had to cool before being charged, extending charge time a bit


The problem I have now is finding #2 phillips bits that actually work. I've bought the store brand at the counter sold loose, Ryobi, Hitachi, Milwakee.
The Hitachi were absolute worthless junk, snapped the tip off every bit on the first screw.
The Milwakee weren't far behind, lasting about 4-5 screws (25-30 if I baby the shit out of it) Bottom line, at the first slip, they're done.
The bits that came with the screws weren't much better, but fell somewhere between Milwakee and store brand.
The store brand were a little better at 30-40 screws
Can't remember any other brand because it's been too long.
