I hold both an amateur license and a conventional ‘itinerant’ LMR license good nationwide.

The LMR license is more useful to me than my amateur license - I can just hand my friends my pile of cache radios and get yapping at an event. As a plus, we can run encryption and other fun things on the LMR license (within the bounds of our emissions) like APCO P25 (Project25) data transmissions.
