Should i join Marine infantry or Army airborne?

Hey so im 17 and i plan to join the Army infantry with an airborne contract or the Marine infantry. The problem is whenever i think i have made up my mind i rethink the other branch and then im back to square one. The thing it comes down to i suppose is that i like the combat and deployment oppertunities that the Army offers but i also like the respect and pride that comes with the Marine Corps. I'd like to hear from some members of bother services and would LOVE to hear from people who were in the marines and army and share their experiences. I was also thinking of doing Marines then Army after, waddya think?
