I take the claimed difference that are based purely on self report with a grain of salt. ("No, I can really see the tiger"....) Even when some people are better at recalling details of a visual scene, there are lots of confounding factors. Do they really have qualitatively different subjective experiences, or just worse memory over all? Or difficulty concentrating? Hard to disentangle these, or even know for sure if they are distinct things.

However, I found Feynman's example very compelling, where the self-report (visual vs. auditory counting) matched up with how visual or auditory side tasks interfered with time keeping.
