As an FYI, Wilflex did for a time make some non-migrating plastisol PCs, I think they were for printing over a DC base? Not sure really but I swear that was a thing you could buy at some point.
Zoo- actually the non-migrating pigments (yellow and red) are to keep the pigment from migrating into another color when trapping. Specifically think old school athletic numbering where you might print a solid number with red, flash, then print white in top of the red. Standard red pigment will migrate into the white.
So why not just manufacture all red with this NM pigment? Yup, super expensive rmc!

No kidding, that makes a lot of sense I suppose.
On the original topic- we mix with PCs here. Best reds for us. Go with whatever brand is consistent and consistently available.
Yes, richer reds through lower activator typically. That said, our ink guy has played around with the DC formulae to the point where he is able to achieve a lot of basic, bright reds with higher activator. Higher activator is more consistent across fabrics/dyes/lots/blemishes in dyes/etc. but higher activator likes to "blow out" your color, acting like a white. My point is that if you want to run at higher activator you can get there with some learning but that lower activator is the easy fix. That and try another PMS to base your red off of, 185c is kinda pinkish to start with. Better, mix one up from scratch with your PCs instead of aiming for a PMS swatch. I don't particularly like any of the pantone reds.
