I would say Navy for a few reasons. You can control you education when you sign up and you can make rate faster than any other branch of service. I got out after 4 years as an e-5 went in as an e2. My cousin went into the Air Force three years before I enlisted and I out ranked him when I got out. For job opportunity when you get out as well as better advancement opportunity and decent food while deployed Navy is best.
