PHPstorm was excellent when I, a Ruby developer (among other languages), had to adopt a PHP codebase.  RubyMine was less impressive, especially with all the enhancements available for Pry and IRB.  RubyMine couldn&#x27;t find method declarations or infer types the way PHPstorm could.<p>So, I stick with Vim for Ruby, but don&#x27;t rule out IDEs entirely for other dynamic languages in a pinch.
