I've always been more plot-driven. It may come with the territory of writing fanfic, seeing as how our main characters are kind of already created for us, but when I think of an idea for a story, I think of the plot first and the characters second. I try to write dynamic characters who change as a result of the plot, and I think I've gotten better at that over the years, but I still tend to focus on the events more than the characters. I am an outliner and a stickler for accuracy, so that fits with the plot-driven profile too.
Some of the character-driven qualities fit me too, especially with certain stories. I think maybe that's the direction my writing is heading in, which is probably a good thing. It's hard to write a good story without a plot, but as the article points out, readers read 70% for character. A story is nothing without great characters to bring it to life. I think the best authors are the ones who find that balance between plot and character.
