The chuck makes anything else I've used feel like a joke. The makita and porter cable chucks are not great. The other dewalts at least did not slip with smaller bits, but the metal 791 chuck is on another level. It's very precise and smooth and grips firmly. The chuck alone warrants the extra cost over the 780. The 780 is only $30 less, which I don't understand, because it's much closer to the 771 than the 791. If you're considering the 780 either save your money and get the 771 which is pretty much as good, or just spend a little more to get the 791 which is a huge step up.
The brushless motor is extremely powerful compared to most drills. According to the internet this drill has an output of about 620 in-lbs of torque. In America, dewalt lists their drills based on some arbitrary non standard unit of output. There's probably some old engineer working there that thinks he knows everything and won't use the same measurement of torque that everyone else uses but there you have it, 620 in-lbs based on converted European (newton meter) specs. Anyway, if the drill bit snags you're going to be in for a surprise, at least I was, and I'm not a weak person. The drill whipped right around and if I had a weak wrist it might have hurt a lot. I guess you could say this is a good thing because more torque = more better (right?) but at any rate just be aware that a lot of drills this powerful have an extra handle, whereas this one is meant to be used one handed. It makes me slightly nervous now but I'm just being more careful. Everything else I've used that has a brushed motor, I am strong enough to stop the drill if it snags.
I can't comment on the battery life because I haven't used it enough to have cycled the batteries or even run one of them down all the way. Based on the old model and typical brushless drill efficiency it should be good. It makes it harder to run out of battery when you can check the charge level and keep the second battery charged, anyhow, just pay attention.
The case seems well made and everything fits well. I might have liked more room to store drill bits (there isn't much extra room, and no designated spot that I can see for storage) but the compact size of the case is useful in its own right.
The light is very bright and has a few settings, not much to say there, but it's more useful than most.
I can't imagine there is anything else out there right now that's better than this drill as far as a compact. I did a lot of research and the next best drill I found was a rockwell that's also sold here for about as much as the dewalt 780. The rockwell also has a metal chuck and brushless motor, unlike the dewalt 780, making it a better choice in my opinion. Bosch is known to make good drills, however their most recent models of compact brushless drills are reported to have frequent issues with the trigger, and they all have plastic chucks. They are relatively inexpensive though, although the torque ratings on the bosch are quite low (in the 400's in-lb) which is even weaker than the rockwell (530-ish in-lbs) and much less powerful than the dewalt 791 which appears to be the most powerful compact brushless available.
That about sums it up, if this drill is in your budget I don't think you can go wrong, if your budget is limited get the 771 because it is half the price and works fine, especially if it's not being used in an industrial setting.
Power wise, this drill is not noticeably different than my other drills. It does feels faster when pushing a bit hard, but my old 3 speed drills applied enough force to burn up or ruin most drill bits. What I love about the DCD791 is how compact it is. It’s nearly half the length of my old 18v drills. Its nearly as compact as my driver. I was also looking at the larger brushless DCD991, but the compact size of the DCD791 is such an advantage that unless I was mixing mortar or boring really long holes often, I would prefer the compact drill. I used this recently to drill some sheet metal HVAC ducts in a tight space, and it was great not having to use my right angle drill.
Dewalt incorporated a lot of good features with the DCD791. I like how bright the light is, and it’s great having the 3 settings. The drill has 2 speeds and while it’s a little rough switching between the gears, it’s less clunky than my other drills and I haven’t had to spin the motor to get it to shift. There are rubber bumpers around the side of the main part of the drill’s housing that help when the drill falls over. The chuck is all metal and grips well. The grip itself is thin, comfortable, and easy to hold tight. This being my first brushless drill, I also like that there’s less noise and no sparks. This comes with 2 DCB203 2ah batteries that have the “fuel gauges” to check your battery life. The charge I received was a DCB112.
With all the features, the best thing about this drill is how compact and relatively light it is. But don’t let that give you the impression that this isn’t a powerful drill. The DCD791 is fantastic and I’ll have a hard time switching to larger drills when needs call for it.
Along with a Wera bit set like Wera Torsion 8600-9/TZ Sheet Metal Bit Set its a tough combo to beat.
