You compared them with Rough Rider and I about spit coffee all over my keyboard!
As for the longevity of RR knives and really of GEC knives we can not tell as they both have not been around for that many years. People tend to forget that GEC is a new company too.Swiss army knives have been produced mainly with machines for decades and they seem to last fine if not abused for several decades, a century even, so RR knives could well last longer than people expect them too. Theoretically the GEC should outlive them, but it all depends on the use of the kinife. I am sure my safe queens can easily survive 30+ years. I have a cheap Chinese buck 110 lookalike which is over 20 years old and still going strong and that was not good quality or expensive.
I have GEC's that are a few years old right now that have already gone for twice their original cost recently.2xTap
