While RCS is the future if text messaging, the Google app has some major shortfalls which make me stay away from making it my default messaging app. The one that i want to point out here is the simplest yet one of the biggest, only being able to pin 3 people to the top of my messages is a deal breaker for me because my current default allows for as many as you want and I have grown accustomed to this. There are other pitfalls that i hope are worked on but we will see. i will update later.
