I honestly believe given the same set of requirements, constraints, and people skilled with their respective stacks, the language and framework wouldn’t make that much of a difference.

Out of the four modern languages/frameworks that I’m fluent in: C++/TreeFrog (played around with it just because I am a masochist), C#/ASP, Python/Django and JS/Express, I really don’t see any difference in my productivity in any of them.
