Comparing Master photographers is pointless. All one should do is evaluate your response to them.
Recently saw an exhibit of Ansel Adams prints and they still take my breath away, almost as if his vision is superior to the real scene. There was one from the 50's that I'd never seen before which surpassed for me most of his more famous works. In latest issue of Lenswork Brooks Jensen talks about how photographers get certain works overly selected to detriment of many of their other works. Adams' pre-40s work is case in point.
I've seen very few Brett Weston prints in person; but do have Art Wright's DVD collection of his images and they are stunning. But my reaction is more intellectual, viewing them as a pictorial koan. Different artist, different reactions.
