I use Gmail for email. Of all the features compared, I use none of them. This review is a FAIL.
Review it based on metrics that can be measured, such as how quickly it opens, how easy to navigate, how easy to organize, etc. Trying to show one handles photos better is specious. I READ email, which is text. If a photo is attached to my email, I click, it opens. I get very few emails with linked photos that are on another site.
