I'd go without the serations. I've never needed them, but i've often needed more force on my blades, and i'd rather push on the spine than have to use the knife to 'chop' things up.

Why not put a wire saw in the hollow handle? I'm sure it is more efficient at sawing wood than serations on the jknife.

BTW, I've never handled either knife, but i have used fixed blades with and without serrations. they are also of a lesser quality than Chris Reeves or Cold Steel, so it may be a different situation.
