I have the Outdoor Edge folder with the regular and zip blades. It's convenient to carry and use, and I skin and quarter most of my deer in the field with it. I will admit that it doesn't hold the best edge though, and am usually working around the limitations of a duller blade till I get to the back half of the deer. Beyond that, I consider it a great do-all knife. The zip blade is a great feature, and makes opening the hide a breeze. I think they now make a version of this knife with the replacable blades, which would mitigate my issues with it.
I also have a nice Marbles fixed blade Hunter that my folks got me for Christmas one year, and that only comes out for bucks and other special occasions. I skun, quartered and deboned an entire bull elk with that, and it held its edge well throughout. It is a fine looking knife, and I consider it a keepsake.
Once it gets the the processing table, a 6" Victorinox boning knife handles everything with ease. It ain't pretty, but does it's job well.
