download opanda iexif from their website and use that by right clicking on a jpeg and selecting 'view exif'
never really compared the two as I don't tend to look at other peoples exif's, only my own, and then only if people ask and I can't remember.
It's a bit like asking the chef for the recipe rather than appreciating the taste of the food imho.
When I looked at pics it helped a lot if they had just the shutter speed, aperture and iso shown. I know that its not going to help me get the same quality of shot but it did help me to understand what worked with each picture.
