This is the best response to the OP's question.
Don't worry about the crew aspect, choose the one that suits the mission you want. If you want an A/A mission with an aircraft that excels at that mission, go C model. If you want a dual role aircraft that is designed to excel at A/G, go for the Strike Eagle. The Mudhens can't BFM for shit against the Vipers and Eagles, but the other guys don't get to rage into a threat zone at more than 500 knots, less than 500 feet, blacked out, at night.
With more than 1500 Strike Eagle hours, I can count on one hand - make than one finger - the number of WSOs who were talking luggage. They know their role, the crew duties are clearly laid out, and we have a good method for setting those straight who have problems figuring it out.
