Probably "regular" vim goes last in that list because the author assumes Windows users are unfamiliar with the terminal. But it can be easier to open vim in the console for something quick or if you're doing something over the network (say, ssh). For example, I use the terminal often for quick commit messages or short edits and consistently for Mutt. Regular vim is easier with Mutt rather than kicking open G/Mvim and then returning to the terminal to send the mail. (You can automate the right return to focus for the terminal when you close G/Mvim, but it's still a bit jarring.) For very long edits on a good connection, I will open sshfs and use M/Gvim, but in general ssh + vim is simpler.
