If you need to create a performant gui app for something very fast, it is no match. It is unfortunate that it has not been embraced by the scientific community. The only benefit of Python + (random) gui layer is that you write something in python and you need to also provide gui. You need to write it with what python provides to stay unified. But that is the only benefit.
