Drabbles are easier. The flow faster and usually I don't think a lot about them before I write them, I just start typing. I like them because I can go straight to the point, and image or a thought I want to write about and let that be that. I don't have a preference between the two. They are just different. Multi chapters require a lot more work, but you can also include that many more things in it. I like writing scenes as much as I like complicated stories filled with plot so I like both types of stories ^-^
