Why do I need RubyMine?

Question

ruby

In Ruby, it seems to be customary to develop in Vim and, optionally, tmux. This is quite convenient. For example, I open a tmux window for each top entity (as a model or controller) of the application, in it Vim with the corresponding file and split with the corresponding test, plus windows for the console, rspec, etc.
However, the very existence of RubyMine gives a reason to think about the imperfection of Vim + tmux workflow, well, key bindings hell also makes you look towards specialized integrated tools.
My question is not only about RubyMine, but about IDEs in the context of Ruby development in general. What exist? What are the best practices? Maybe there is an IDE with such a killer feature that I will forever forget about Vim? What will I gain from the IDE and what will I lose? Share your experience.

I advise you to use RubyMine for a few hundred hours, then go back to your previous tool and freak out at how you could use it.

Moreover, RubyMine has a vim mode , which allows you to use all the hotkeys you know, but at the same time, all the functionality of its functionality.
