I think part of the reason it looks "off" is the angle of the handle relative to the blade. Take a look at the Khukuri Dynamics page, and you'll see that for the most part the handle is either "in-line" or "curving away from" the spine (or rather, the line created by tracing down the spine). On this one, it's "dropped"...or, lower than the spine, and it almost looks like it angles up (vs. down on most khukuris).
I, too, am curious about how it compares. Might be a hard test though, since your hand will adjust to each one. I'd recommend chopping hard with an H.I. khuk for about 10 minutes and then immediately picking this one up and continuing the chop. That should make for a good comparison.
