I think it depends somewhat on the language. For Ruby I prefer Emacs and don't see much benefit in autocomplete. But for Objective-C & Cocoa, which is admittedly a somewhat extreme case, autocompletion is a godsend.
But autocomplete is only one feature among many I appreciate in a good IDE. I'd also hate to give up a good visual debugger with integrated breakpoints, direct links from compile errors, etc. I know you can hack a lot of this together in Vim or Emacs but after 15 years of doing just that I don't miss it when I'm using IntelliJ or XCode.
