I have watched salmon being fileted with an Ulu, and I think they are overrated. I don't see it doing any better of a job, or any quicker than a good fillet knife. What I do see is people having to get their other hand closer to the blade, increasing the chance of a accident.
I am inexperienced at cutting land game, or skinning so I can't comment there, but as for fish, give me a good long blade.
It's apparent you've never watched a competent Ulu wielder tackle a salmon. Seeing those in the know filleting large Kings with an Ulu is a display in efficiency and efficacy of motion. They also work well for fleshing bears.
