Personally, feature-wise they're best of bread. IntelliJ is the best Java IDE I've ever used, and ReSharper makes Visual Studio brilliant.

That said, they aren't always the fastest, and don't do anything to dispel my hatred of Java UIs.

I used WebStorm to do node.js for a while, but haven't renewed my subscription as it didn't provide me much extra from vim. The jQuery/Web stuff I've done with WebStorm was pretty good though.

I recently switched from Aptana to RubyMine and it is really good. The only drawback is that in my experience it really needs a powerful workstation to give its best.
