Is Visual Studio auto-complete significantly different from IntelliJ or Eclipse? There are many great editors an the continium between gedit and Visual Studio, such as Sublime, hell even vim and emacs have autocomplete plugins.
But VS auto-complete was a breath of fresh air afterwards.
I appreciate Eclipse's openness (and I tend to work with open source languages), but I must admit that purely examining the quality of the tool, Visual Studio is leagues ahead.
