This varies greatly between writers. I've self published two scifi novels, and I found I wrote faster when I didn't edit as I went (even when subsequent editing was factored in), but fast isn't always what you're going for. And I don't personally need (or want) tools to push me not to edit.

But where editing really kills you are for those who get stuck in "endless" polishing of the smallest little details before they have anything, and as a result never get anywhere. Then having tools to push you past that can be useful.
