One important thing that is often not mentioned is the lack of operator overloading. In Elixir if you have "a + b" it means "a" and "b" must be numbers for the code to succeed, which narrows down the possibilities significantly. Compare that to Python, where "a + b" applies to numbers, string concatenation, and any object that implements the __add__ or __radd__ magic methods, it becomes a nightmare to type.
