Dewalt right now.
They do the job, and the price is right. I'd have gone Makita except for the issue they all suffer from. The lights are always in the wrong place
I have no idea why they insist on doing this, every manufacturer does. Usually worse than no light, since they light up everything but the bit.
Dewalt's impact has 3 leds in a ring around it, so I get nice light, in an actually usable format.
If Makita would quit putting the lights in useless places(trigger guard) I'd probably buy one, but in small dark spaces those lights are nothing but aggravation with the exception of my dewalt impact.
I'd prefer Makita, despite the extra cost to switch yet again, and the loss of some of the functions I appreciate from dewalt since it would let me standardize even further(including my dremel tool, right now I have the Dremel brand Dremel which is fantastic compared to my usual jobmate/mastercraft ones.
The other advantage of the Dewalt line right now is that they use a single standardized charger for 12v charging, thereby eliminating the need for one for 12v and another for 18v.
Grip is much better, balance as well and the battery shape are better(they pack smaller, and don't roll away, so less likely to go overboard)
They still have belt loops too, which I use to secure a lanyard too, Makita rep couldn't figure out a solution for that.
If my rotary tool was the same, the 2nd charger wouldn't be an issue since I'd still have eliminated one, but I'd really prefer if Dewalt brought out some more tools in the lineup(Vacumn cleaner and rotary tool especially a heavier duty one like the Foredom).
As a final bonus, they have repair depots everywhere. If my Dewalt tools fail, I can drop them at the repair depot that day in town.
That alone is worth a lot if you need the tools for work like I do, if I break it, the depot is less than 10 minutes from the boatyard and the price is hard to beat if you're just working on your own boat. Unless you're really anal about standardizing everything(like I want to) and spending a bunch of coin to do that, or have needs for tools outside the standardized lineup, the other upsides of Dewalt are hard to beat, Makita and Milwaukee are great, but for useability, service and function if you just need the basics(drill, impact, right angle drill, LED lights etc)I'll take Dewalt any day.
