Depends on what you want to do, both in and after service. Every service is good in its ways, and bad in others. Find the one that works for you. But on the advice of my wife, STAY AWAY FROM MEDICAL. DO NOT BE A DOC. They'll work you to death. If you don't mind tight spaces and do well with Tech, there's Navy nuke. My old job. But it has its problems as well. High divorce rate, HIGH BS factor, etc. No matter which service you choose, make sure it's a good fit for you. Don't join the Army if you hate walking. Don't join the Navy if you hate water. Don't join the Zoomies if you want a cool uniform. Good luck, and for myself, I'm proud that some STILL want to serve.
