I would phrase that question as "Am I editing one file, or a project of files?". As a Vim user, who previously only used IDEs for java projects, I now use IntelliJ for HTML/CSS/Javascript projects too. If you learn the refactoring and completion shortcuts, I believe it beats VIM at most multi-file projects. If you install the Ruby plugin (also built by JetBrains, for their Ruby IDE) you get support for Sass - and they've just announced support for Less and Sass3 in the next version, including command completion and jump-to-declaration. http://blogs.jetbrains.com/ruby/2010/07/whats-mining-leaner-css/ http://blogs.jetbrains.com/ruby/2010/07/whats-mining-leaner-... The Scala plugin doesn't seem too bad either, but I haven't used it extensively. It already has some simple refactoring features. They're also working on a Python IDE, which is in beta, so the Python plugin will get fairly good too.
