AZK and KCR are basically the same thing. Both contain "fragments" of HTML code to be rendered using a web browser or a native HTML rending engine. The main difference is that KCR is delivered by Amazon and has DRM while AZK is created by users and is meant to be side loaded.

It is supposed that the Kindle for iOS app was forced to use AZK/KCR format instead of KF8 (azw3) because of Apple's rule preventing iOS apps from containing their own HTML rendering engines. (KF8 is based on an outdated version of webkit.)

It is unclear to me why Amazon would be using KCR format in Kindle for Mac (and possibly Kindle for PC.) Perhaps it is being used to add support for one or more languages that KF8 does not handle well.
