If I could do it all over again, I wouldn't go AMDO, mainly because I'm not prior enlisted. I mean, I got to OCS as a 23 year-old, and people kept asking me if I was prior enlisted...I started thinking, should I be? I've since fixed the situation by getting picked up for lat transfer to the CEC, but that's another story.
Also, AMDO wasn't my first choice, I tried for NFO, but my -9.00 made sure I didn't fly. Also, every other rare non-prior enlisted guy I talked to that is an AMDO took it as a fallback option.
To answer some of your questions:
Maintenance Chiefs - I can tell that they definitely treat me different than the LDO/CWO crowd, which I think is total BS. In AMDO, it's almost as if you're expected to be prior enlisted. When I was about to check in, our MMCO told our SK1, "you know, you're getting a young guy [as MCO]" In any other community, they wouldn't point that out.
Paperwork: It's not endless, but that's what your job is. The MMCO is by far the busiest ground pounder job. My gripe with the paper work is that there's no variety. It's not like being an NFO, getting to fly, then landing and dealing with your AV/ARM Div O paper work.
What I like best: It's not SWO
What I like least: The work
I think most prior enlisted guys like AMDO over the enlisted life...it's a career progression, for me it wasn't, because I was fresh out of college.
AMDOs under pressure...I haven't felt it, because I'm not the MMCO. He feels the pressure, I feel the boredom.
As for AMDOs being outsiders by pilots senior or not, there is a lot of truth in that. However, I've been fortunate to be in an S-3 squadron, and the pilots/NFOs are cool as hell. Also, since I'm closer to their age, we have a lot more in common and I hang out with them back home and inport.
Your average prior enlisted AMDO is older, married with kids, so what is he gonna say to the 24 year old NFO who just checked in from the rag? If you make an effort to fit in, you will. However, I hear some of the super hornet guys can be A-holes, and I see their MCO hang out with their LDO MMCO all the time, and the MCO is younger than me, so that can't be too fun.
Hope I answered your questions...and good luck, I seriously hope you get NFO.
