I've done a lot of work in both Go and Python recently - using httprouter and flask, respectively. Python libraries are a lot more mature. But in bigger projects, debugging in Python can be incredibly painful. I think it comes down to the fact that Python is a really complex language. On the other hand, Go is so simple. (And you may hate it for this, at some points.) Sometimes, I find it more helpful to think of Go as a higher-level C rather than a Python competitor. The syntax is easy and familiar when you get started, but I think you will miss a lot of the Go beauty if you are looking for a "faster Python".

tldr; Go is not Python, but it is still beautiful.
