Any benefits of having USAA or Navy Fed checking account compared to private banks?

I posted this before couple days ago in another subreddit and was told to come over here.

I am enlisting soon and need to provide bank information. I was told about USAA and Navy Federal and trying to understand if there is any benefit of having a checking account with them versus having a checking account with any other private banks?

Only thing I found is that you might get your pay check early with USAA and Navy Fed, (And get car loans) but any other benefit? I have no problem with my current bank so I'm trying to figure out if I should get an account with them or just use the one I have. Also, between USAA and Navy Fed, which one is better? Thanks!
