I like both, but when I see something impressive and highly detailed, and it's been done traditionally, i'm floored. I'm also better with traditional means, and I don't mind the time it takes. I always feel that working digitally takes some immense amount of time. i've also yet to find the right digital software to use.
in the end, i think i like a combination of both. I prefer penciling and inking traditionally, but coloring digitally. that gives me more chances to decide on colors in action, and not just on the side of the paper i'm working on.
I'm liking digital art a lot more lately, but the thing I don't like about it is that you generally don't have an original hard copy of the finished piece. You can print it however many times you want, but with traditional art you've one singular, original piece.
