Personally I would go with the trunk. Unless you remove the seatback and cushion of a rumble seat, you would have much less room for stuff in the trunk. I think many people that have rumble seats in their coupes or roadsters wish they had trunks. To me, rumble seats in standard coupes, business coupes and special coupes are not all that great in that the people inside the car can't easily communicate with anyone in the rumble seat. In a roadster or sports coupe, there is a flap that allows the two groups to talk. Just my opinion.
