I have hunted with a bunch of PHs, and know several more very well. Have also sat around during evenings drinking beer with up to half-a-dozen very experienced guys, and heard them argue.
But the majority have stated that they much prefer to see a scoped bolt-action come out of the gun case when a new-to-them buffalo hunter shows up, This is because too many have seen bullets misplaced on buffalo due to two factors:
1) Iron sights, which often don't provide an adequate aiming point on buffalo in thick, shadowy cover.
2) A double chambered for a cartridge the hunter can't handle, due to recoil and/or heavy trigger pulls.
And buffalo hunters probably out-number elephant hunters 100-1 in present-day Africa.
