I don't care what the "torque" output of the air ratchet is. Initial loosening, and final tightening is going to be done by me the old fashioned way....leverage on the ratchet or by some other means (torque wrench perhaps). An air ratchet is a nut runner. It doesn't break free stuck bolts or supply final torque for a fastener. Whether an air ratchet outputs "30 ft lbs" or "70 ft lbs" means little to me. All it generally tells me how much it will hurt when my knuckes get trapped.
An air ratchet does indeed fit places other tools don't. An impact, even a 3/8" impact, takes considerable space to operate and can be useless under the hoof of many cars. Lot's of times I don't feel like using a 12pt wrench in a tight space. Oftentimes an air ratchet will clear and make my life simpler especially when you have limited degrees in which to swing a wrench. P-steer pumps, AC compressors, water pumps/pulleys, and belt tensioners saw their share of air ratchet use.
Air ratchets are just tools that saves time in the hands of the knowledgeable. Use an impact when you can, an air ratchet when you can't so you can get that car done before the service advisors and shop foreman start whining.
He nailed it - I agree with every word.
I have an IR1033 - a 3/8" drive tool in the space of a 1/4" drive. Made in Japan. Only 6 1/2" long and 1+ lb. At least 20 years old and never a problem and I use it A LOT - more than a 1/2" Impact by far. Looks like it is replaced by this:

As mentioned - it is a nut runner - which is so much of car work. Critical loosening and fastening calls for other tools, but this little guy saves so much time. And my 69 year old wrists and arms appreciate that.
Don't knock 'em if you don't have one.
A little more guts with this one:
