I prefer written tutorials with pictures. A lot of times, video tutorials are filled with talky-talky fluff that I don't care about. It can take two, three, five minutes to get to the actual tutorial section of the video, and even then, it takes foreverlong to see the parts. You have to sit and wait for everything, while with a written tutorial, you can take a look, read what you want, save pieces of the tut into a notepad document, glance back at it later, jump around where you want to...
It's why I prefer manga to anime, too.
