Interesting to read all these facts (that I probably should know by now) and learn all the small differences and origins. I've only experienced 3 suits in person FX, ATA, and CFO, so I can't really give any better opinion about RS or AP than what's been discussed already. All I can throw in is I agree having a suit that fits you is really the key thing to look for. I think as far as total complete accuracy, if you have a squad of troopers wearing RS, AP, ATA, TM, and FX standing together...the FX one will be the only one that sticks out without close inspection. From what I've read about RS, I'd probably choose it, between the two, if money was no object, but that's just me.
