The RMS set-up was the first Mopar offering of a R&P, a K member offering more oil pan clearance, replacing TB's with coil overs allowing much better header clearance, and a reduction of some weight mainly by offering a bolt on disc brake solution.
It was initially never marketed as a better performing IFS for any road course application. Early on the Mopar crowd decided in groupthink it seems that TB's are old, Coil overs are new, and therefore they must be far superior in every application.
This thinking happens often it seems.
I cornered Bill on this topic nearly two+ decades ago, and he basically admitted as such, but reality is, people make up their own minds and Bill had a hot profitable shiny new offering to sell, and it was not bad.
It seems though even with the above, bang for buck has caught up to it.
This video here IMO is hardly useful nor effective as a real "comparison". It's simply a review, uncontrolled, not empirical, on three different cars that seem to only share in common is their shiny paint and manufacturer.
But once again, people will believe what they want to believe.
