Like Joe says, Its personal preference and probably what you were taught, or observed from others.
But here's my take, I have been using a 110 for all of my field work on deer since the early 70's. Don't have a 119 user, so don't know about using those in the field.
I have no problems doing the first cut on a deer, going inside and cutting loose internals and rolling them out, carefully removing bladder and rectal parts, without splitting the pelvic. Then quartering one up and into the ice chest.
Last few years, I have used a 121 for some of the quartering and removing the backstrap, due to the longer and thinner blade.
It is all a matter of how you have learned to do it, and how much practice you have had.
Since I have owned my own hunting place in heavily populated (deer) country since the early 90's, I have had mucho practice. I have tried a few various different knives but the 110 is the one I go to.
One of the things is, I have several that are with me in the field. When finished field work on a deer, that 110 gets wiped off and into the ice chest. It gets cleaned up back at camp and another one goes on the belt.
And while I am at it, I prefer the nylon/cordura horizontal carry sheath for the belt, or may not even have one on the belt since the truck and pack is never very far from where a deer goes down. But not everyone has this luxury I know.
I did try a droppie blade once, and where Joe had trouble sticking a clip where he didn't want it, I had the similar problem cutting through the hide with the droppie. Seems to me the blade got to the skin before I was ready for it to. But again, it is a matter of what you are use to. My take on clip versus drop is most skinners are clips. And won't get off into a whole nother thread on that. Again personal preference.
You just gotta do and learn for yourself. And I have had old hunting buddies change their methods after watching the way we do it.
fwiw....
