Dewalt at home, Dewalt and Snapon at work. Snapon hands down the best but pricy.

I picked up an electric Harbor Freight 18 Volt 1/2" impact wrench cheap.
Not good for breaking even 100 ft-pound torqued on lug nuts at least in a timely manner.
It is good for.... jarring the lugs enough for a breaker bar to loosen them easily enough for the HF impact to take them off.
Far as torquing the lugs, i use the HF impact to get them in the ball park and then follow up with a torque wrench.
Those are the safe methods i prefer when dealing with lug nuts as i'm not getting paid by the hour like a shop mechanic.
Do not use an impact wrench alone either electric or air to torque the lugs.
You'll either under torque or over torque them possibly even snapping the stud.
The one good thing about cheap electric impacts like my HF is its dam near impossible to snap a stud by over torquing.
It also loosened some other stubborn rusted-solid bolts/nuts easily.
One other thing use only 6 point sockets designed for impact wrenches if you value your socket set and lug nuts.

You can use the impact to tighten if you use a verified torque stick, or my preferred method, which is to use the 140 stick and finish them with the torque wrench.

I have a 20 volt Porter Cable that works like a charm on lug nuts. The box sez 330 ft-lbs torque. Had I not already had the small PC impact driver and drill, along with the circular saw, I probably would have gone with the Dewalt or Milwaukee. Makita and Bosch are good choices too.

I hate it when a shop uses an impact gun to install tires. Anyone who does this is no mechanic I’d go to. If you need an impact gun to get the lug nuts off, they’re over-torqued.

I never said anything about needing an impact to get lugs off, but it is certainly much faster, which is why I use one.
