With kits changing so may the tools. Back when I built my 6A before prepunched holes and early, slow, short battery life chordless drills it was a no brainer to use air drill.
I love my air drill and still use it even to drill just a few holes that I do these days. I never have to wonder if I have a charged drill ready to go and I don’t think of the hose as an issue since I have it on a reel since I use it to air up tires on plane, car, truck, bikes etc all the time.
And I agree with Bob about making me know I am building an airplane plus I love the sound of air tools.
