I like to use r for data analysis, but also have experience with Python so it is not limiting in any way. The GUI is very intuitive and easy to learn. It's hard sometimes to see what is going on behind the scenes (in terms of code), however this can be remedied by looking at some of the documentation online or asking questions from other users who are more familiar with the platform. There isn't anything that really stands out as being bad about R-brain enterprise analytics platform. For our needs we were able to get up and running quickly without having a lot of technical support needed. We had access to all required tools and packages right away which saved us time getting started.
