I try to ctrl+x ctrl+c in things that aren't Emacs. Whichever you choose you eventually learn it well and it seems so easy that it's hard to see what the advantage of an alternative might be good for

No one can argue against you as you know how to use the tool. Vi and Emacs are both perfectly capable editors, both have been used to make huge amounts of code. Both are great for updating configuration files, both beat the simple editors when it comes to syntex highlighting and encouraging correct updates
