The NT50AE2 is the best buy because it does the three things trim carpenters care about: it drives a wide range of nail lengths, sets depth accurately and lets you pick the firing mode. Nail lengths from 5/8 to 2 inches cover thin trim, baseboards and furniture frames. Adjustable depth lets you sink the nail just below the surface so putty hides it, and set too deep it punches through the face of thin trim.
A selective actuation switch changes between sequential firing, where you press the nose to the work and then pull the trigger, and bump firing, where you hold the trigger and bump the nose against the work for speed. Sequential firing is safer and more accurate, while bump is faster for repetitive work like paneling. Against the Metabo HPT NT50A5 pro model with its aluminum magazine, the NT50AE2 keeps the same nail range at a lower price.
A pneumatic nailer needs a compressor and an air hose, and a few drops of oil in the air inlet before use. Set the regulator to about 70 to 90 PSI, and test on scrap to find the minimum pressure that sinks the nail. Too much pressure drives the nail through thin trim and wears the driver. Fill the nail holes with wood putty after nailing and sand lightly for a clean finish.
