There is an interesting article in the Ed Forum by Artie on ISO. His favorite MIII ISO is 400 and in bright sun he might drop to 320 or so; but he mentions exceptions as well - hence, often the answer is "it depends"
On balance, ISO is a critical part of the exposure calculation, but I tend to set it and forget it most of the time (there are exceptions / e.g., conditions change fast) and find other ways to get around limitations. I use flash, play with shutter/aperture/tripod, I shot in morning and evening light, soft but adequate and I put my efforts into image quality and image detail - hope this helps - just my field techniques.
