The first part of this course provides an overview of ES vs CX.
A simple way to compare the features of Dialogflow ES and Dialogflow CX is to build the same chatbot using both.
In the second part of this course, I build a very simple decision tree chatbot in ES first, and then explain how to build it in CX. While this covers only the basics of ES and CX, it is a very good way to think about the state machine in CX and compare it with the implicit state machine in ES.
