As it says above, which one do you use and why? Like, I've used Mail for a long time, and it's okay; quite functional, no real issues with it. I recently have access to Outlook for Office 2016, and...it seems okay. I guess. I don't really know what the differences are, and online reviews are sketchy at best as to differences. So, I'd like to ask my fellow Mac users, which one do you prefer, and why? Bonus if you use the mobile versions on iPad or iPhone (which i suppose I would; I'm the sort of person that likes to use the same set of apps on all my devices, if possible).
