For an inexpensive truck/pack/loaner knife, I like the Cold Steel Pendleton Lite Hunter and Canadian Belt Knife styles that can be bought for around $17 on eBay 24/7/365.
Either of those knives with the blades touched up and a Sagan Saw is all a person needs to field dress a deer. It isn't a lifetime knife or a knife that will ever be an heirloom, but it is quite serviceable.
I'm not a fan of Moras, particularly those with a carbon steel blade, as the grind makes for a thin/fragile edge and the carbon steel Moras seem to rust almost instantly.
It's basically a case of personal preference. I like Moras because of the thin edge which makes touching up the edge very easy. They aren't fragile for anything that I will do with a knife. They will cut wood or split ribs without any problems. I won't be cutting wire or heavy bone with one. I don't care if the carbon blades rust. I like that they sharpen easy and the rust won't hurt anything since I won't let it go for months without cleaning.
I would be perfectly fine using either the Buck or a Mora to field dress an animal. I do think the plastic Mora sheaths suck.
