Eclipse 3.4 with the RadRails plugin. I think it works better then the standalone RadRails 1.2 right now. I'm guessing when 1.3 comes out I will need to look at the standalone application again.
How to get it to work: http://forums.aptana.com/viewtopic.php?p=21964#p21857
Add http://update.aptana.com/update/studio/3.2/ to the list of plugin repositories and install "Aptana Web Development Tools".
"Reboot" Eclipse.
After some time, the Aptana Start Page will show up (or you can start it from the Help menue). From this page you can add and install Aptana RadRails 1.0.2.
I like Textmate in Mac, and E in Windows ( textmate clone ). Aptana is a really good IDE also, but I find that it's heavy and can become sluggish after a while.
Surprisingly I like using a few Windows Command Prompts, Explorer, and many Scite instances (with a custom configuration). Not really an IDE but I've found it more flexible and useful than any other IDE that I've tried.
Ruby In Steel For IronRuby I haven't used it myself... (A plugin for Visual Studio I believe)
I like Komodo for PHP and Python development but its support for Ruby is pretty thin. I've only recently started working with Rails and Komodo has been disappointing. I'm giving Aptana a try based on the accepted answer.
