It will really depend on how much money each is offering, what rosters and what T&C's each have offered, persoanlly if I was a Plane driver I would go for the Polar Air Cargo Only because I would end up killing the odd potential Arrogant git who just happens to be on my business Jet that I would be flying.
Being a Freight dog is awesome according to many of my Freight dog friends as its night flying and usually the T&Cs are usually pretty good as well and no back-chat or special requests from so called execs.
Hope that helps and I hope you can provide further info so we can further advice you, anyways welldone and good luck.
