For developers who responded "I am a developer by profession" and used C, C++, Java, and/or Python in their dev environment, VSCode tops VIM, which tops Sublime, which tops Emacs. Every time!
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.
Yes, certain programming languages are biased towards certain editors. Java users will overwhelmingly use Netbeans/Eclipse/IntelliJ, C# users will overwhelmingly use Visual Studio, Lisp users will flock towards Emacs.
