The most important 'feature' that comes with a large camera body, for me, is that when I operate the controls, I don't lose my grip. This means I can operate controls at the same time, in quick succession, etc. When I'm wanting to use all the tools available to me to get the perfect shot, I want to be able to reach them and operate quickly. On my smaller-bodied Fuji mirrorless, there's no viewfinder and I almost always shoot in a fully automatic mode. This is great for holiday photos, where it's much more about the memory and much less about the 'art'.
