Mmmm in my experience, I think especially if you already have the tools then it's worth the investment to try and become more comfortable with digital art. Basically re: what darthmangoose said. I did my first comic here on tapas with traditional linework and digital colors and the process of scanning and prepping the art for each page ended up being more hassle than worth. I went through a bunch of different methods over the run of the 70 page comic-
at first I would use mechanical pencil, ink over it, and erase the pencils before scanning (much like when I do traditional marker art). I found that it was hard to rid the paper of all of the eraser shavings though and so a lot of my scans would pick those up which led to a lot of pre-coloring editing. Erasing also just takes a lot of time, especially on the big 11x17 paper I used.
So then I tried moving to non-photo blue colored pencil for my pencils because you don't have to erase it afterwards. That part was big time savings and no more eraser shavings on the scans was nice! But I found that I had a hard time seeing my sketches clearly because the color was so light and so I ended up having a difficult time inking and missed a lot of little details.
Finally in the end I would do the sketch digitally and then print them off on 2 sheets of printer paper and use a light box to ink (at this point there weren't that many pages left so I wanted to finish the comic off with the same line quality, otherwise I would have just digitally inked).
All throughout this too, I only have a small scanner so each page required 4 scans to digitize and then I would have to piece them together (thankfully Photoshop does this automatically for me tho).
The reason I went through all this trouble was because at the beginning I felt the same- my digital art skills were shaky and I especially didn't like how my lineart turned out on the computer, so I felt it was faster to get nice looking drawings traditionally even with all the extra steps. While I was doing the comic though I decided to practice my digital art skills on the side. After... maybe a year of that I felt like my digital art skills were finally on par or better with my traditional art ones. Now, 2 years later, I can make pages digitally much MUCH faster than traditionally.
Not only do I not have to go through all those extra steps, but I also have access to all of the digital shortcuts like undo, copy paste, being able to rescale and rotate things rather than completely redraw, etc. I could never imagine going back to traditional for anything other than standalone illustrations or very short comics. Anything that's moderately long, the time savings on digital is just too great.
