My procedure for selecting an editor starts by taking an online class and using whatever tool the expert is using. I figure their reasons for using said tool in a given stack is probably more reasonable than anything I can come up with in my comparatively limited experience. That said, it looks like this:

Visual Studio - C#

Notepad ++ - Any text file I need quick access to, cut/paste

Visual Studio Code - Trying it out to replace Notepad++

Android Studio - Native Android Apps

WebStorm - JavaScript and front end projects

IntelliJ IDEA - JAVA
