This can and likely will turn into a bit of a spirited discussion. There are some strong feelings regarding both GEC and Case and they will likely manifest themselves over the course of the dialogue.
I own far more GEC knives than I do Case so that in of itself should tell you my stance on the matter. Most modern Case knives that I have handled lack the substance that GEC produces in their knives. GEC provides better consistency in quality, better cover choices, and better action.
That all being said, I do have some '60s and '70s vintage Case knives that are on par, if not better than some of my GEC knives. Case produces at such a volume that they can afford to have QC issues, lackluster covers, and anemic actions these days, but that wasn't always the case (no pun intended).
I think that despite the concerns related to the cost of GEC knives, they present a tremendous value and not only will they maintain that value but in many cases, they appreciate considerably.
It is important to note though that GEC is not infallible and do have some issues but they appear few and far between and I have heard pretty good things about their warranty and customer service.
