I would recommend a 3/8" impact and 3/8" drive impact socket set before I would recommend an air ratchet. The air ratchet can be a knuckle-buster when loosening or tightening fasteners. Ingersol-rand makes a nice 3/8" impact, and as far as the sockets go I would recommend a any set that has a life time warranty. I have seen many different brands of tool in the shops that I have worked at, even some from harbor freight (which I am not a fan of). I would just recommend something that you can warranty if the need arrises. I personally have a snap-on 3/8" impact and socket sets sitting in the top drawer of my tool box.
