I agree Alex, the stack is not that important. The choice should be a balance between available developer skill (in and out the company), product requirements and time to market.
See Elixir for example, it's a great technology but experts in Elixir/Erlang are not easy to find so, as a freelance developer, if I were to convince a company to let me create a web app with that I would also increase their risk of failure the day I left.
Another thing to keep in mind: in 2017 with Heroku/AWS Elastic Beanstalk/Digital Ocean Droplet/Docker (pardon the generalization) it's not impossible to be a polyglot company, always keeping in mind the product requirements.
I would also recommend this article: "Is Ruby Too Slow For Web-Scale?" speedshop.co/2017/07/11/is-ruby-to... which also stresses the concept of context when we talk about speed

TL;DR the best stack is the stack you know
