I have found small flaws with every framelock I have ever fondled, aside from my Mnandi and small Sebenza. Other framelock is include Strider, Emerson, Benchmade, Spyderco, Kershaw, etc. Granted the only other one that was the same price as the CRK is the Strider SnG, which is a very common EDC for me. It has lately developed some very slight vertical play though. I have a temp fix on it right now, but it will probably, eventually be sent in for service.
So initially, yes, my experience has been that CRK knives do live up to the hype. I have not put one through the ringer the way I have the Strider and the Emerson though, so I can't say anything as to thier performance over time .
Like you, their designs just don't really appeal to me, so at present I don't own one, ones that I have owned have been traded away, but not for any mechanical deficiency, just because other similar priced knives have more appeal to me.
I think I might someday buy a small sebenza though, unless CRK comes out with a folder that I like better.
