Air tools are good sometimes. When you need them, you need them.
There are impact air ratchets. Nice tools for limited uses.
Battery impacts with 1/4" hex chucks are ubiquitous, but if you're serious about useful tools, you can get 3/8 and 1/2 in impact wrenches, which are highly recommended, and then you can consider a battery ratchet. Milwaukee makes a good 12v one, dont think Id want an 18v one because of the size/weight of the battery.
