In my experience Emacs with Quack (or with Geiser, or with both) indents exactly the same as DrRacket. That's not to say there isn't some corner case where they differ, but it sounds like you're noticing more than that. Try Quack or Geiser. That's also not to say DrRacket is bad. It feels a bit slower to me when typing, than Emacs. But it has all the cool tools others mentioned. You can also use Emacs most of the time, and use DrRacket for the tools.
