I switched to Eclipse when I was playing with Android (because it has the necessary SDK). I loved the code handling - no extra, unnecessary tags like I remember and caused me to leave WYSIWYG editors in the past. Nevertheless, code-completion, refactoring suggestions, code-coloring, and formatting, have helped my coding and productively considerably.
