I prefer an editor that works how I want it, and so I use my own editor because I found I spend less time tweaking my editor that way than I do trying to bend an "off the shelf" editor to my will (I started writing it when I realised my emacs config was more lines than it should take to write an editor). Sometimes it breaks. That's fine - I can fix it trivially. But because it's my own, I also put up with things in it I wouldn't otherwise, because I know how to work around it. I also get a level of pleasure from gradually taking more and more control of my own tools that I'd never want to give up.
