For a good high end rebuildable air impact, I'd suggest an IR 2235timax or a good aircat like the 1150
The tool truck impacts are good and rebuildable but you'll pay more for them with no real added benefit
IR 231c is a great mid level impact. Bigger, heavier and weaker but can last forever and enough power for most jobs
With an air ratchet, kinda depends on what you use it on. I've got a snap-on far7200 and it has some balls (70 ft/lbs I think) and has run out rusty/loctited bolts a cordless wouldn't touch, but equivalent snap-on new is like $400. The other half of the time I don't need the power and think about adding a cordless ratchet
Seems to be alot of hate towards air tools lately. Only 2 areas I've seen cordless beat air is convenience of no air line/compressor and noise
air is still more powerful, lighter, smaller, spins faster, and can take more abuse
as an auto tech that works in a shop with supplied air, air still wins over cordless, for 1/2" impact. The high torque units are just too bulky and heavy IMO. I do have a cordless 3/8 impact and an impact/driver that are used frequently
