ScandaLex,
Can't say. I have not used iOS 6 (I think that is the newest version).
The one big problem I have with the generic mail app on Android is that when in areas with bad connection, all the mail you have already deleted gets redownloaded over and over again. Never had that problem with Apple mail.
I am not here to start a war of Apple vs. Android mail. I am in a unique position that having Apple devices all my mail synced much better with iCloud using Apple mail over Android. I also think that SPARROW MAIL for iOS was one of the best email clients ever made. It was bought by Google 6 months ago so I am praying for an Android version soon.
