I'm using both Ruby and Go a lot (also Elixir, PHP, Bash and others).

I wouldn't even say that they solve different problems for me, it's more a matter of how I need the problem solved. If I need something that runs on other OSes than my Linux box preferably with as few dependencies as possible, Go. However, I can probably code it faster in Ruby, so if it only needs to run on my machine or if I know Ruby's available where it needs to be run, then I'll probably go with Ruby.

I think, instead of arguing which is better, the argument should be about whether they're useful. And for both Go and Ruby that's an "absolutely!" from me.
