I've always preferred partially serrated blades but it was mostly asthetic. I do like the advantage being able to saw through vines and green branches, and I stink at sharpening so a serrated edge worked better for me at hat task, and left me with a partially smooth edge that has never let me down.
As I do a little more bushcraft,I'm finding that a fully smooth edge is better for things like batonning wood. My DH and DS got mea smooth edge fixed blade for Mother's Day, and I quickly fell in love with it.
It has slighty edged out my trusty old Ruko, with the serrated edge on the spine of the blade.
