I enjoy the 300 mags for the reasons noted. They hit accurately, hard at distance and penetrate deep--the crux of an all rounder.
The 338 doesn't have the flat trajectory but hits like a jackhammer and penetrates to the vitals with the big tough mushrooming bullets like the Swift Aframe. Kind of like a knockout punch!!
