Should I use R or Python?
Since R was built as a statistical language, it suits much better to do statistical learning. Python, on the other hand, is a better choice for machine learning with its flexibility for production use, especially when the data analysis tasks need to be integrated with web applications.

Why is R so bad?
R is terrible, and especially so for non-professional programmers, and it is an absolute disaster for the applications where it routinely gets used, namely statistics for scientific applications.
