Another argument for the .350/Maxi/.360-class of cartridges is ergonomics. They can be chambered in light, well balanced, handy little rifles that are an absolute joy to carry in the thick stuff, and which don't scream at you and smack you like a .35 bottle necked cartridge would if provided in a six pound (or lighter) rifle. (Astute handloading of said cartridges notwithstanding - how many hunters/shooters really do fall into that category anyway?)

My little Martini .357 Maxi, 26" barrel, weighs in at a scant 6 pounds. It's a pleasure to shoot 200's at sub-2000fps out of, but would be a nasty little SOB at higher performance levels. And those 200grain/1900fps loads generate around 1600ft.lbs. of muzzle energy, death to many four legged creatures at "normal" woods ranges. And on top of that, the little thing is comfy in the hands all day (note absence of sling swivels):
