With the qualifier "working knife," I'd vote ZT/Hinderer. It's not as cool looking as the Hogue, IMO, but I own two other ZT knives that are both built like tanks. The ZT's basically gonna be a poor man's XM-18, w/o flipper, and w/over 200 posts I'm sure you know how high the regard for that knife is around here.
Frankly, I'd like to own both, just like you, but I'm on the pre-order list for the ZT myself; Hogue will have to wait.
