Google Play Real-Time Multiplayer Support Pros And Cons

Hi Guys,
I Want to add real time multiplayer Support in my racing game.
I would like to go with google play services as it is free but i have some questions and i want to know pros and cons of using it in a unity game such as CCU Limit and other limitations and features.
Please Help, Thanks for your time!
