PS I don't know how my tone came across in the above post, but I don't want to sound too negative. I think depending on age and what your other options may be there could be better choices. If you are lucky enough to get on with NJA you WILL have a good job that I think will only get better.
You will not beat NJA with JOB security!
If I were you I would make a list of priorities and assign them a point value.
Job security 10
Pay 9
QOL 8
Bases 7
etc....
Try to guess what you think may be the value at certain jobs and add them up. That is how I made my decision. It was very close and a hard one to make. Who knows, I could be crying in 10 years for leaving.
Good Luck!
