Pneumatic tools offer the user longer tool life and lower operational costs.  Tooling costs less generally speaking than costs for battery tools.  Pneumatic tools don't provide the same portability benefit than battery tools--but if you are strapping at a single station and have air lines available pneumatics may be your best option.
