unless price is a serious concern, I agree, a smith is the choice I would make. I've never been as comfortable with another brand. the subtle differences between smith and other brands add up to the others not being useful to me.
If you have even the slightest expectation that you will someday actually need a magnum weapon, then, don't waste time on getting a .38. The .38 is a bit underpowered for a boar. You shouldn't hunt anything bigger than raccoon with a .38, imo, and when you are looking at human targets, the .357 has enough power to turn questionable hits into stops.
We aren't talking about just 100 or so fps difference; the .357 magnum is a huge step up that you will really need if you are hunting, and it will be much safer to use in combat.
Oh, and don't forget, the .357 is still versatile.
