WHAT SHOCKS TO BUY: KYB VS Monroe VS Bilstein's

That's what I'm trying to get at, one size fits all for the
RCD shocks regardless of vehicle model, weight, torsion bars or
handling improvements.

No, they don't. RCD Bilsteins have different part numbers for cars at standard ride height vs lowered. The part #'s are different for the rear shocks on A bodies vs E bodies. It's not a single set of shocks across all models. Not only that, but I've already mentioned several times that the Hotchkis Fox shocks work better for the 1.12" bars I have on my Duster. I think the Bilsteins are better suited for bars that are 1" up to about 1.06" than they are for bars larger than that. Not that they don't work well for 1.12" bars, but the Hotchkis fox's work better.

And, the argument doesn't hold up anyway. The reason they're more expensive is because of improved valving in the shocks compared to cheaper units. Better valving means the shock can produce the correct dampening over a larger range of inputs. Now, that doesn't mean they're the best for every situation, but I would take a set of Bilsteins over a set of KYB's on any of my mopars regardless of model, weight, torsion bars or other improvements. And I have A, B, and E body's, with small blocks and big blocks. And I've run Bilsteins on my Duster and my Challenger, they work great in both applications even though the weight and wheel rates are different.

I mean, you can run Bilsteins with /6 bars if you want. I bet they'd be better than a set of KYBs even then. But if you're going to run /6 bars a set of Bilsteins is overkill and a waste of money, 'cause the handling is going to suck regardless of how good the shocks are.
