Impact Driver vs. Hydraulic (Quiet) Driver: Is Quieter Worth It?
A standard impact driver gets its extra twist from a metal hammer and anvil smacking together inside the tool. That's what makes the loud rattle. A hydraulic driver, sometimes called an oil-impulse driver, does a similar job but sends those pulses through oil instead of bare metal-on-metal hits, so it's built to be quieter and smoother. Both take the same 1/4" hex bits. To compare them with real numbers, we read Milwaukee's own pages tonight for one of each on the same M18 battery platform. We haven't tested either tool hands-on, so there are no ratings here.

We left the hydraulic kit's battery model out on purpose. Tonight its page data listed two different battery pairings, mixed in with a related kit version, so check the "In the box" section yourself before you buy.
Milwaukee says the hydraulic driver runs up to 50% quieter with 3X less vibration than standard impacts, and calls it the quietest cordless fastening option on the market. Those are the maker's own claims against an unnamed baseline, not our measurements.
What the numbers tell you
The big gap is torque. On paper the standard impact driver is listed at more than four times the hydraulic driver's maximum torque (2,000 vs. 450 in-lbs). The two are close in size and weight. So the trade is simple: the hydraulic driver gives up a lot of muscle in exchange for less noise and vibration.
Which one to buy
Get the standard impact driver if you'll build a deck or fence, drive long structural screws or lag screws, or want one driver that handles anything around the house. For most first-time homeowners, this is the safer pick.
Consider the hydraulic driver if noise really matters to you, for example working indoors in an apartment or condo, near a sleeping baby, or for long sessions of drywall, cabinet or trim screws where vibration wears on your hands. Just know it isn't built for the heaviest fasteners.
Either way, stay on the battery platform you already own, and if you already have batteries, look at the bare tool first. See drill vs. impact driver, compact vs. full-size impact driver and bare tool vs. kit.
