Na, It's harder in the Air Force than anything else. You need at least 10 years experience in air crafts and 5yrs or equivalent in flying hours
well tbh, the marines are the most hardcore so if you're into that then God bless you. But money wise, It's Air Force all the way, as well as Navy. But wow, you're pretty young and already decided. That's great, hope you have a great time wherever you choose to go
