Navy or Marines JAG/JA

I figured I'd post this here because I assume many of the people in this subreddit have interacted at some point with Navy and/or Marine JAGs.

I am currently a college undergrad who will be applying to law school next year. I am certain I want to become a JAG of some kind, and always kind of have been. I am looking most heavily into the Navy and Marines, but am considering the other branches as well. I plan to make a career out of being a JAG (obviously if i like it as much as I think I will.)

I am attracted to the Navy because I really like maritime law, love being out on the ocean, and really like the navy base locations. This has always been my first choice.

I am attracted to the Marines for the culture, a lot of the Marines I have met I like as people. My legal mentor is a Marine.

My grades are pretty great as of now so that is not a restriction. My lsat will be above average. I am in physically good condition, I probably couldn't get a great score of the pft right now but with some months of training I am sure I can (was an athlete throughout high school).

Between the Navy and Marines which branch will give me the best:

-Quality of life

-Stability (Moving locations less)

-Career progression.
