I have the Makita XST01 'Cordless Oil-Pulse Driver'
https://www.makitatools.com/products/details/XST01Z
After hearing my brother in law's regular Makita impact driver, the sound it made was more than I wanted to deal with, so looked at some videos online. I don't remember actually taking in much of what the reviewer was saying, but really wanted to see it being demonstrated. After buying the oil-pulse model and driving deck screws it really is pleasantly quieter to the point that you don't need ear plugs. The biggest effect the oil has is right when the anvil hits, the sharp transient sound is more spread out in time and assaults the ears much less.
This unit is rated for 355 inch pounds of rotational force. The regular brushless drivers from Makita list ratings between 1400 and 1550 in lbs. That looks like a big difference on paper, but it easily drove every screw I needed, including some 8" long SPAX construction screws and smaller Simpson lag bolts. There are 4 power settings: Soft, Medium, Hard and an auto adjusting mode. 95% of the time I use Soft and it has enough power to easily set a 4" deck screw. The other modes will drive it faster, but I like the better control, especially when contending with Philips head screws.
For me, it's a great option that I appreciate. YMMV. Luckily YouTube is a click away.
