I would stick with the pneumatic stuff, light weight, more powerful, easy to handle, easy to maintain. The electrics just don't have the power, especially when you are driving nails through hardwoods such as mahogany. The DeWalt is ok but it is bulky and heavy, and is not to easy to work with in confined areas. I have used a brad nailer but sometimes it is over kill, the guage of the nail is to heavy for finer work. I mostly use a pin nailer & glue for all my exterior & interior work.
