Tried them all.

Spark, Cloud Magic, Boxer, Air mail, Outlook (you get the idea). All great apps making short work of email when setup correctly. For me, however, and this comes down to personal preference, Dispatch is the only one Ive landed on over and over on the IOS platform. Surprising, Dispatch even beats out mail clients with corresponding Mac programs (Airmail is very powerful and comes in at a close 2nd - especially patterned with theyre Mac email client). For the iPhone, however, nothing quite comes as close to perfection as Dispatch.
