I have dealt with only a couple of lemons from GEC, but that was out of the 10 or so GECs that I have owned which were all near perfect. I returned one to a retailer for unacceptable blade play, and the other I sent to GEC for repairs. The one that I sent to the factory for repair work came back to me flawless, and is good as new (which left me thoroughly impressed with GEC's customer service and their lifetime guarantee).
I have only owned one modern made Case which was a peanut, and the fit and finish was right up there with GEC's fit and finish. All of my knives right now are currently GEC, and they are all near flawless if not perfect. I think there is a good reason why myself and others keep buying them besides the fact that they can be very addicting (I'm not a serious/real collector, more of an acquirer/user).
I personally lean more towards the design of GEC knives over Case knives, but I still wouldn't hesitate to recommend, or buy a Case CV folder. For my personal tastes, I much prefer GEC for the solid feel and for the variety of selection they provide. GEC knives just feel more solid to me, and they are generally more aesthetically pleasing to my eyes than any of Case's offerings.
