The best feature is the Kony Studio, which is the product that is used to develop interfaces.
With the new VM releases, it is a faster product with more abilities that benefit the user.
Game testing and the API for apps are good.
Ability to use different frameworks.
Oracle Autonomous Mobile Cloud Service helps us to deliver the application much more quickly, as it comes with built-in platform APIs for storage, push notifications, analytics, etc.
IBM MobileFirst has one of the most feature-rich admin panels.
I like Its capability for developing hybrid applications, with an ability to integrate device-native code as well
The initial setup is not overly complex.
