It depends on what do you want to achieve, but in general, the language ecosystem is i.m.o. more important than each of these. I.e. I really don't like Golang, because it has lackluster support for functional programming paradigm. I feel that writing code through composing functions (map/fold/reduce mostly, maybe some walk, as I often do data transformations) makes me feel productive and producing less errors in my code. In Go, I have to write for-loops. On the other hand, the libraries and the rest of the Go ecosystem is really nice, especially if you target kubernetes and there is the feeling of 'there is one obvious way to do it', and I kinda like that. So I write Go. Hm, reading this after myself, maybe that is some argument for architecture of infrastructure?
