Yeah, I agree that Spyderco and GEC are apples to oranges. Both of these companies make up 80% of my collection. I have quite a bit of both. With GEC you're getting handmade (not custom though), you're getting the pleasure of a hafted knife, you're owning something that has soul, and you're getting Peter's Heat Treated 1095 which performs very well for what it is.
Downsides are limited production (this year has been an exception) and an occasional proud tip (not sticking out but I'd still like many of them to be lower). Never had blade play.
With Spyderco you get unique designs and either good stainless or boutique steels.they make great users and some are flashy. The warranty is better too.
In the pocket knife size both are easy to carry. GEC will have more resale value but GEC knives will look like hell long before your spydie will. Spydies have a 200% better edge out of the box. GEC takes more maintanence. More people will compliment your GEC. GEC still knows how to hide pins. If you're using your knife often, the life of your spydie will surpass your GEC. GEC in my experience doesn't do locking knives well.
So yeah, give or take. I love both.
I own an assisted knife and am embarrassed to admit I enjoy it.
