I think Titan is correct.
In any case, both locks use the same general principle -- blocking the blade using a cross pin, which would have to be sheared in order to unlock it. At some point, you have to wonder "how much strength is enough"? Even if one of the locks eventually proved stronger, if the other was fairly close, who cares?
At the point, it's time to look at other factors, most importantly, the RELIABILITY of the locks. Based on my experience with liner locks, the biggest question is: will this thing accidently unlock on me? For both locks, the answer is probably "no", unless you get your thumb on the lock release button and engage it by accident. This is a matter of ergonomics and likely different for everyone's hand. So far, I can't get my Axis to accidently unlock, even when I'm almost trying to throw my thumb around. When I get my Carnivore, I'll see how I do on that one.
