Do you like to fly high and fast or low and slow. Do you like to pull G's or hover. Neither is better, it is what you like that makes it better. Pay is nothing to write home about no matter what you fly. If you are going straight civilian, fixed wing is a better option. Much cheaper training, much more job opportunity and opportunity for slightly higher paying jobs (generally speaking) in the FW community. There are much fewer helicopters in the world, thus fewer helicopter jobs. Most require quite a few hours as well.
