The RR's tend to run cheaper and they offer configurations you won't find elsewhere.
Over the years I've been watching, Oly's have run hot & cold. Some are great, some uh, less than great.
What RRs cost depends of course on what you want, but they can usually be had for substantially less than advertised, suggested retail. Many match shooters (me included) consider the CMP gun the bargain of the year! The flattops are stompin' shooters as well, from all reports.
I'm trying to convince myself I need more of 'em, knowing full well I need another bellybutton about as badly
