To be fair, there's a bit of ambiguity in what question is being discussed.

1. What development environment do you use most (IDE)?

2. What editor do you use most?

3. What editor(s) do you use regularly?

Personally, my day job currently has me working in Java, and I use IntelliJ for that. However, I use Emacs on a daily basis _as an editor_; especially in the case where I need to look at, move around, and manipulate files quickly.

If I had to pick one of them to keep and one to give up... I would be sad, because the fill different roles.
