I purchased Mail Pilot and Unibox because of this article — with the intent for one of them to replace Sparrow (which is amazing, but there are bugs that will never be fixed). I liked Unibox more. It has a way of minimising the complexity of my inboxes. Being able to see all the attachments to and from a particular person is very nice. Mail Pilot feels a little less polished and less smooth. It also makes a very strong effort to educate me (popups and explanations are attached to everything, intro tutorials and videos) but I still found it a little confusing to navigate. Initially the "New Message" button simply did not work until I restarted the app. Unibox did not make much effort to teach me. And despite completely rethinking my inbox I've found it straightforward to use. Unibox seems to place the information you are looking for right where you expect it (for example, dates fade in and attach to the scrollbar as you swipe through your emails, changing as you scroll). It's very cleverly designed to show and hide information as you navigate, without showing too much. If you don't mind switching to a people-centric interface, I'd recommend Unibox. Mail Pilot seems aimed more at people who like to organise their email (the reminders system, completion checks, sorting). I just like to read my email and write, and Unibox does a great job of it.
