Case has a few patterns that they really own. IMO, nobody makes a slimline trapper like Case.
But Case has had some ups and downs. Sadly, it's not entirely unthinkable to get a dog.
Rough Rider has been fairly consistent with their traditional models, they offer a wide array of patterns that aren't readily available elsewhere, and are inexpensive. They use decent steel. Some of their jigging patters are remarkably well done and unique. Their F&F seems to equal Case more or less. Personally, I like the RR sodbuster patterns better than those from Case.
It's little details where I get really critical of both Case and RR.
This isn't a matter of getting what you pay for, IMO. Quality-wise, traditional knife making is very mature technology, and Case doesn't hold any magical knowledge. So I buy based on those little details, functional and/or aesthetic factors that help me decide my purchases. I recently bought a small RR lockback Barlow. Didn't keep me from also buying a Case single blade mini Trapper.
