I said Traditional, because I love nothing better than to sketch with just paper and pencil and writing, when I'm planning the chapters and story line, I find it easier to just jot things down as I please. Having said that, I write my actual chapters digitally on Microsoft Word and I have a Graphics tablet and Photoshop where I like to do digital pieces... I guess I love both
For drawing, definitely digital - reason being that what motivates me to draw is my frustration at not being able to physically see what I'm imagining... like my imagination isn't good enough and I need to make it real... The more real, the better, and digital software can achieve that realism and accuracy far easier than traditional techniques which does have certain limitations with vividness and degrees of detail unless you're insanely skilled.
In theory anyway. In reality, I think I'm just completely useless without ctrl Z.
Funny thing is, I write and draw. Creative writing/RPGs and such [I do my best to refine my writing into an artwork], and sketching. With writing I'm more connected to it when I'm doing it digitally. But with drawing? traditional definitely. I'll need to get a tablet that shows me the image before I could feel any sort of connection to it like I do with traditional art [I can never get the hang of drawing on a tablet and watching the screen. I have to be able to see the tip of my pencil/pen hitting the page and see where it's going to feel comfortable drawing]
A lot of people seem to like traditional for drawing and digital for literature. I'm on of them, and I really understand. With traditional on the subject of art it's more limited than digital, thus control is at a much closer reach, IMHO. With literature it's easier to be on the computer than on the notebook. I mean, the cleanup alone would convince writers to shift to digital. There's also the researching, the thesaurus-and-dictionary-ing, and the easy editing for writing. So yeah.
