IMO, one of the benefits of a 44mag over 357 is the commonly available ammo is more suitable for woodland use. Most of what you find is 357mag "on the shelf" is designed for self-defense against humans, where the 44mag's commonly available stuff may not be up to the full potential of the cartridge, but will easily handle anything in the Mid-Atlantic region. To me, it's like buying a truck. You *can* get a truck rated to tow 5k lbs and use it to tow 4500lbs, but you're safer buying one that can tow 10k pounds. While you'll never use the full capacity, you're well within its performance limits.
As for revolver vs semi, I like running my first shot as snakeshot during warm months. That's a bit trickier with a semi, assuming the snakeshot is even available for that chambering.
If I were to get a semi, it would probably be a 10mm though.
