Which one do you prefer for serious Ruby on Rails development?
I've been using NetBeans for PHP and Java for more than year, which works really great, but the Rails support isn't imho good enough. I often have problems with code completiton, where it doesn't find most of imported gems and functions and it's also pretty slow.
On the other side, I tried JetBrains RedMine, which is super fast compared to NetBeans, but I don't have such long time experience with JetBrains.
Lots of people recommend TextMate, so I've tried its Windows port e-TextEditor, which I think is some sort like PSPad ... good for small edits, but not so convenient for big projects.
The last I found people mentioning is Aptana Studio, but I have absolutely no experience with that one.
So my question is, which of these IDEs do you recommend for development of enterprise class applications ON WINDOWS.
The reasony why I'm asking is if there are any problems that you came across while using that particular IDE, that might not be obvious when someone just tries it
Please answer only if you have some experience in the field, not only if you "tried it"
btw I don't think this one is a dupe, since it's much more specific than those other questions
