I use Sublime Text for all my Rails development. It's fast, easy to use, and has a ton of features. With Sublime, I can easily search and replace text, make multi-select edits, and customize the look and feel of the text editor. The sidebar also comes in handy when organizing projects and jumping between files. Beyond standard text editing capabilities, Sublime also offers great support for Rails. With packages like Rails Snippets, SublimeLinter, and Ruby Slim, I have access to snippets and syntax highlighting for Ruby, HTML, CSS and more. Sublime Text is my go-to for all Rails development.
