Since I work both on Windows and Linux here are my tools.
IntelliJ as an IDE, mainly Java/Android but I use it too for any other supported language (shell scripts, python, whatever, if there is a plugin I use it), sometimes even for some single files, since I have it open nearly all the time.
Notepad++ for any quick edits on Windows.
vim for quick Linux edits (mostly stuff that needs root)
Edit: Sometimes I need a hex editor, for that i use Bless.
