I have the 2755B which is the compact 1/2" with a ball detent (the most recent gen might be a friction ring). Anyways, this impact was able to remove the lugs off my F150 (150 ft-lbs torque spec).
With that said, I also have the bigger 2763 and there is a noticeable difference in the time and number of impacts required to remove the lugs. But I tend to grab the 2755 (and hearing protection) when rotating the tires.
