I have the more powerful Ryobi impact and it's great tbh - however I don't believe the torque rating on it (it's still generally plenty for suspension work including pressing in bushes etc) and am not sure it would undo a hub nut to use the example above. An air impact absolutely would, as would a higher powered 230v tool.
It's pretty compact though which is where the plugin tools can sometimes fall down, I also had a cheapish plug in impact completely fail after a few "good" uses where the Ryobi still seems in perfect condition a couple of years into relatively heavy (for home) use, I've stripped all 4 corners of both my focus and fiesta suspension wise including wishbones and well sized strut bolts, replaced bushes on the rear of the fiesta that need to be manhandled in, plus many other small jobs where it's used to buzz things off.
It's also pretty handy to just have around the house and be able to swap a battery in then build decking, fencing, swing sets, drive into brick (carefully) etc
