I use IntelliJ with the ruby plugin (which is identical to rubymine). Very nice, but I often resort to the command line for running git commands. The main advantages over "nothing" are syntax highlighting, code completion, being able to search all the ruby libraries (for your RVM). Downsides are the debugger works "most of the time" and bundler seems often munged up (it works, but reports errors).
I've also used <a href="http://www.aptana.com/products/studio3>RadRails</a&#...; which is also pretty good. Frankly, I like jetbrains products because the support is awesome and they just seem to be better at guessing my intent (with intellisense), but I wouldn't kick RadRails out of bed in the morning ;)
