I've always felt if you're going to go for a massive overbuilt knife, you're buying it so everything is exactly that "overbuilt". I just don't see the point in buying a folder with huge stock, heavy in pocket etc but it still has a frame lock. That spring tension barely gets any stronger when you beef up the frame of the knife. That's why if i'm going to put up with the weight and size I want the thing to be as indestructible as it feels even if we're talking "abnormal or abuse standards". In that vein i prefer the 4max, SR1 and the actual AD-10 customs from Demko. I still love the Adamas and other tanky knives tho.
When other companies start bringing out massive overbuilt knives with actual strong (and unique?) overbuilt locks that can't fail from average abuse I will start looking at other makers. Because at the end of the day overbuilt knives are a bit of a novelty, they don't cut things better or carry better, they're made to give you that sense of strength and indestructibility, and I just don't get that feeling from any kind of frame lock.
