Just curious, as a quick example, I take photos of many subjects, I have no specialty, I lean toward Landscape, Architecture and Sea scapes with occasional forays into astro photography and Night scenes, But Generally I just love to take photos.
For general photography covering most subjects which would be the better option.......?
ISO 200 - 56000
or
ISO 50 - 12600

assuming all else was the same EG sensor size lens aperture etc?
