So, I've been meaning to put a bit of info up about this for quite a while, but I've been busy not having time to even sleep. I've finally got time to put up a small review (honestly more like a long opinion).

Most of my workers use DeWalt. I had 2 Makita guys, now I only have 1 Makita guy (he moved, not switched brands). Several of us made the jump to LION DeWalt, specifically for the brushless versions because we're literally drilling thousands of holes through dimensional lumber and we're eating several sets of brushes per job. The new, higher capacity (and much lower weight) batteries were a HUGE success. Heat dissipation is awesome, with the metal body of the big drill (their biggests, the DCD-995) barely getting warm, where the 18v XRP would actually smoke if pushed too hard. The power of the 995 is phenomenal, MUCH higher than the DC-950/970 we all used before. It's said to produce around 725 inch-pounds in gear 1, much lower than the 1090 inch-pound rating of the Makita DHP481 (I bought one for my remaingin makita guy), yet it was able to power through things that the makita would quit on. I believe this is due to the more conservative over-current shut off that makita uses, which probably means it will last longer.
The 20vMax impact doesn't perform noticeably different than the XRP 825, other than being lighter. I don't like the new ergonomic shapes, the smaller handles where unnecessarily shrunk, the small rubber bumpers tend to fall off very easily, and we've had 2 impacts crack the battery base away from the handle from drops. This has NEVER happened to any of our XRP tools.
There is/was a HUGE design flaw on the DCD995 brushless hammer drill though, it caused 3 of our units to completely fail.
They've moved the LED from it's location above the trigger to the battery base. However, they didn't fill the space left open, and when the trigger is depressed, there is a straight path for foreign bodies to enter the inside of the drill. When drilling straight up, which is very common for electricians routing wires through the top plates of walls, the wood shavings fall right into the hole and damage the inside of the unit.
We spend hours cleaning them out without taking the drill apart (which would ruin our warranty), but eventually they stopped working. We tried taping over the hole, which would eventually bind the trigger and cause huge headaches.
Finally, after 3 months of calling DeWalt and threatening to switch all ~100 tools we have over to the new Milwaukee Gen 2 stuff, they informed me that the problem had been fixed, and they were sending me a new drill for free. They didn't replace the other 2 units, but they're still under warranty so they'll probably be replaced when we get them into the repair shop.
So, beware if you purchase a DCD995 (which I HIGHLY recommend), that it's the newer model with no opening above the trigger. Simply squeeze the trigger and look.

What sort of work do you do?

I've been using the 20 volt impact driver and drill for about a year now, love them both. One of my guys is a die hard Makita fan, and even he switched teams after using the DeWalts for a while. I also picked up the 20 volt chop saw, it's sweet little tool.
Try out the new 5 amp hour batteries if you haven't yet, that 25% increase seems like it adds hours of run time to the tools.

Looks like he is some sort of communications or electrical contractor.

I don't have brushless yet, might start picking up some Ridgid stuff as the battery warranty is pretty appealing. Or wait for it to get to the black and decker level of tools as I have some B&D 20v stuff.

Having used DeWalt, Mke, Makita, I am very happy with my rigid stuff, and they have given me a few free batteries. though, i have never had any problems with the newer lipo vs the old style batteries.

Isn't Rigid a home depot brand?

Not sure why that would matter? My uncle was big on them, and I really liked the way their hammer drill worked compared to my Milwaukee. Of course I ended up getting a Milwaukee Fuel roto-hammer, and it wipes the floor with any cordless SDS roto-hammer I have used.

I still like DeWalt cordless stuff, but I feel like they are coasting on their name while Milwaukee eats at their fan base by releasing some pretty impressive cordless tools, particularly in the 12v sector.

It is all mostly Chinese-made junk now at this point, so I feel like the "big 4" cordless tool argument is moot. Granted, I have only been in construction since 2012, but I constantly surprise old timers that are stuck in the old days and thinking cordless tools are a novelty.

Depends on the tool and what you're doing with it. A cordless rotohammer would be worthless to me, but a God send to anyone doing limited drilling in tough locations. It's all about having the right tool for the job.

I'm still sold on Dewalt cordless gear, the 20v chop saw they just came out with is a very handy tool for doing trim. The 5 amp hour batteries are pretty sweet as well.

Thanks for the writeup. I've had a makita driver for 5 years of home use and when it dies, I'll be very particular in replacing it, since having a solid cordless driver has been priceless.

I wonder if a little bit of carefully formed instamorph could seal those trigger holes.

Yeah, the first time I used mine was in 3 layers of block, drilling 7/8" holes, it was a godsend to not have to drag cord all over the place. It went through the batteries very quick, as the second layer of block was poured, but I have lots of batteries, so keeping one charged on deck was very easy. I still use the rotohammer when I am going to be doing lots of tapcons. The drill is very overpowered behind the 3/16" bit, but I appreciate the zero effort required.

I got my 5Ah battery over a year ago, and it has been excellent for the high drain tools such as the rotothammer. Now that Milwaukee is coming out with a 9AH, I assume DeWalt will follow suit shortly.

Right tool for the job indeed. I have no use for a chop saw, but it seems like Milwaukee is geared towards my trade, where DeWalt is geared towards yours.

Most of my rotohammer work is chiseling off pier heads, then drilling 16 3/4" holes 16" deep into the concrete, a battery powered tool would keel over dead the first day.

I occasionally have to drill hold downs through existing framing, I have a 5' long bit that's an absolute beast.

It's only available at HD in the U.S., but is actually owned by Ryobi - it's their upmarket tool line, like Dewalt is for Black and Decker.
Sorta right, the same manufacturer makes many brands of cordless tools including ridgid, ryobi, craftsman, and others. That company owns only the ryobi brand. Emerson owns /designs ridgid.
