Gmail:
Ancient slow app start and ui.
Default mail:
Push is great but ui is ugly.
Mailbox:
Great ui and push for me. But mails with conversations are missing and useless.
Sparrow:
Everything obviously amazing including making default client but there is not push(Expect cydia tweak but it has to be in background)
I really don’t care push that much(I check mail every 2-3 hours) so
