Editors

I've tasted quite a few editors, like emacs, vim, awk, etc.

Many people think that mastering one editor is much more important than knowing many without any expertise, I can't agree more about this opinion.

However, given all these editors still live, there must be some killer features lacked or weakened by other editors when we talking about each one.

Taking my experience into consideration, I recommend people to use these editors according to specific situations:

situation	what to use
command line	vim
column editing	sublime
project management support	atom / vscode
easily-using and extensible plugins	atom / vscode
general editing on Linux	emacs
general editing on Windows	notepad++
report or batch operation	sed / awk

atom or vscode?

Hard to say, but I think Atom looks better and editing experience on it is more fluent. Plugins on VSCode are easier to acquire and use.

emacs or vim?

emacs is an awesome killer editor on GUI while vim is the one for CLI.
