In the reserves, people's enlisted paygrade vs their age and their life experiences is all over the map compared to active duty. Mobilizations can be all over the map too- if you're a reservist who is a lot older than the typical active duty, early twenty-something E-4/5/6 and you go on a mobilization, there will be inescapable moments when people assume that you need adult leadership by virtue of you being "just" another enlisted dude. Unfortunately at that moment, nobody is going to care that you have a masters degree, or if you are a health care administrator in a major department in a big hospital, or if you're a licensed engineer, or a police detective in a medium sized city, or that you're studying for the bar exam or the nurse pharmacology exam, or whatever your usual thing is in civilian life... If your military job is very specialized then those moments will be fewer and farther between, but they're still gonna happen. Wearing an officer rank is like magic- people bug you a lot less and that's just how it is.
Also, a lot of active duty people are unaware that sometimes enlisted reservists have full plates with their real job/family/life commitments. You'll get a lot of sideways questions, "buuuut you have a degree so whyyyy don't you get a commission uhhhhh I'm so confused why you don't do that?!??" That's another one of those things that are just how it is.
Thinking way ahead to a reserve retirement is if you retire as an E-6 (all of them in the reserves) and you did the minimum plus one or two deployments, a typical retirement check is a few hundred bucks a month take-home. If you start as an O-1 and retire as an O-4 and worked a similar schedule, then the check might be several hundred bucks. Neither is enough to live on, of course. Funny thing is if you're seventy years old and your main income stream is from your long, successful civilian career, how much do you care which of those military retirement checks you get? Straight active duty people look forward to retirement checks of thousands of dollars a month, but many of them don't understand the rules for reserve retirements. What you will care about is that both have access to the same healthcare at the same cost- that is a big deal to most people who stick it out in the reserves.
