Hi Razvan, thanks for you interest in my article :)
As with all languages and frameworks it all depends on the development speed (learning curve) and your personal needs. Go offers a wide range of frameworks/libs like Mux, Fiber, Gin and Echo.
The best way I can reply to you is to take a look at the numbers here:
go.libhunt.com/compare-fiber-vs-mux
I also suggest that you take a look at all the other libs I mentioned here (for example if performance speed is a key component for your needs - take a look at Echo -> echo.labstack.com/cookbook/crud) and find the one that suits you best for your needs :)
