It doesn't have to be measured to 7 significant digits in a scientific way. But if you spent a week trying out various editors every now and then for the kind of work you do, you should at least be able to make a more informed choice about which editor to use. Or you may discover functionality in another and see if you can get it in your current favourite.
I've interviewed people who were exposed to Nano at school, and have never tried out any other editor. They are missing out on productivity improvements available in many other editors. More middling of the scale I've also interviewed someone who used Eclipse as their first editor and has proceeded to use it ever since despite not working on Java projects any more. That isn't bad per se, but I rank someone higher if they at least try out others every now and then.
