Why do you say that 4mer_FMF?
After reading that article, the m390 is definitely appealing over s30v
Blade shape. Handle geometry.
The G3 is awesome in the grip shown by Aquaholic.
If you like to move your fingers onto the blade "skinner style" (sorry, I don't know the correct name for the grip), the G3 doesn't work so well (kinda bad, actually IMO). Excuse my poor pic trying to show what I mean.
I'm sure you are much more proficient at field dressing than I am. But back when I used to hunt frequently, I spent a lot of time with this sort of grip. The BM's I mentioned work great with this grip due to handle and blade shape--not just because of the forward spine jimping. They were designed to be game knives. See where my thumb is in the pic I posted? Now go look at a good pic of the Hidden Canyon and you'll noticed they even milled a place in the scale for your thumb!
For full transparency, I've handled the BM's a bunch, but not purchased or used them--sadly I don't hunt much any more. Still, I wish I'd had them "back in the day."
The G3 is a better all around utility knife, which is why I have one. But if you're looking for something specific to your purposes, I'd still point you toward the BMs. That's even taking into account M390 vs S30V. Just my opinion, FWIW.
I think you'll find S30V vastly out performs what you're used to.
