There's nothing wrong with the Milwaukee Fuel.
I bought the drill a few weeks ago. It is simply amazing. It has a much power as my 1/2" corded DeWalt. The overload protection will instantly stop the motor to protect it. That's really neat in the "2" speed. On "1", it will still feel like it is going to tear your hands off at the wrists if you lock it up. There's a reason it comes with the side handle (which is something I've NEVER had a use for in a cordless drill before).
The first job I did with it, was to use a 1" twist drill, to put a hole in a piece of 3/8" mild steel. On the "1" speed, pushing as hard as I could (braced against something that I could push off of), all I had to do was pull the trigger, and watch the chips keep coming out of the hole. I was simply unable to stop the bit with any amount of pressure.
The link you supplied, was to the impact. I played with that at an HD display, and was seriously impressed. It has three speeds. Kind of an electronic speed range.
At the moment, I only have 12V Bosch impacts.
#1 on the 18V fuel goes real slow. Nice for not damaging screws (same results I would get on the 12V Bosch, if I teased the trigger).
#2 is a little faster. It reaches about where the Bosch is all out.
#3 feels like it will be fine on looser lugnuts. I was driving 1/2" lags into 2x4s with ease, and blasting 3/4" holes through them as if I were using a much larger drill.
Now, here is a catch. If you want the maximum torque out of the drill, you need to buy it with the larger batteries. With the impact, either size battery will get you the maximum results.
