Eclipse when writing Java - you can kill an ox in 6 seconds with the refactoring tools ... unfortunately coding anything in Java is like killing an ox - there's a huge carcass and a funny smell when you're done

notepad++ for everything else (HTML css JavaScript erlang) - fast - light weight - tabs - syntax highlighting

+1 for Eclipse. Then again, I use Eclipse for nearly everything, just because it's what I'm familiar and comfortable with. So even if I'm coding Groovy or Scala or Python or Javascript or Perl, more of than not I'm using Eclipse.

I agree with the fact that Eclipse is excellent for Java, and unusable for anything else.

I hate them all.

And I cringe every time people mention Visual Studio as "the best". I intend to make my own at some point, because I have yet to find a single one that meets even 1/2 of my primary desirables. Eclipse comes close, if you count plugins and can find them, but it's the epitome of bloat.

All except an old, free version of TacoEdit, which has since gone paid. The free one is bad, has inaccurate highlighting, no autocomplete, really squat for JS code, but it's fast and lightweight, and runs code as you type it. Utterly fantastic for rapid prototyping. I boggle when I realize I have yet to see any other web-oriented IDE do this, and don't bother pointing out Komodo; its live updating is cool, but buggy, and you can't break the preview window out.

To step away from IDEs a bit, TextMate is a phenomenal editor, and I end up using it more than any IDE when I'm not doing .NET coding / in Windows.

Good shout on TacoEdit, glad I discovered this.

I use Komodo Edit as an IDE, and Notepad++ for miscellaneous edits. It's nice to have Notepad++ as a second editor on a second monitor for comps and the like. Netbeans and Eclipse are nice, but a bit kludgey for my taste. I do use Qt Creator for the random C++ project.

No IDE is perfect -- if it were feasible, I would love to take bits from each of the above programs and mash them up into one master IDE.

Netbeans has grown quite nicely in the last few years.

Visual Studio with Resharper. A bit slow but really makes C# coding a breeze. NetBeans when coding Java, a great IDE.

Intellij IDEA.

More powerful and reliable than Eclipse, but not free (and also a bit uglier).

the only IDE i use is when I'm working in a smalltalk environment. That is an IDE. Everything else I've used that gets called an IDE has been a pale comparison. When not using smalltalk I bounce around between vim, emacs and textmate depending on the task.

Visual Studio + R#

With one caveat: You better have a beefy computer!!

I am way more productive from the command line.
