There are as many opinions and recommendations as there are people. I love Elixir more than the mentioned two (that’s why I am here and not on pythonforum 
One of the low hanging fruits/benefits of Elixir is the fast amount of build in functionality, the focus on the happy path and the code is easy to read.
Python is easy to write, flourishes on some specific areas but for a lot of things I think Elixir does better. Go has the benefit of a single binary to deploy and run and is faster. But in the end; Elixir is the one that combines many good things of other languages with little drawbacks.
