IDEA for everything?

I'd like to know how IDEA users handle their workspace.

Do you:

1. Install language plugins (Ruby, Python, Go, etc.) for IDEA.
2. Install RubyMine, PyCharm, GoLand, etc.

As for me, I prefer to have one IDE and a bunch of plugins. In fact, IDEA provides more SDK for plugins, according to the Elixir plugin page (projects, modules, building).
