I have used emacs, Eclipse with RDT, and RadRails and Aptana Studio.

I am currently using RubyMine 3.0.1 from JetBrains.  It is the best for me so far.  Be warned, it is commercial, but so far this has been a positive experience.  The price is nice for our company.  There is an evaluation version available.

I will also be looking at RedCar soon

but I have no experience with it yet.
