KDramas were my gateway to Asian dramas, but I have recently started watching more CDramas. One reason I tend to watch more KDramas, and it has nothing to do with show quality, is simply because there are generally fewer episodes. I can commit to 16-20 episodes of the average KDrama but a lot of the historical CDramas extend past 50 episodes. I honestly don't have the attention span to commit to something of that scale. It is one of the reasons I started watching KDramas in the first place. I appreciated the story being told to completion in what is equivalent to one season of a US series. The other difference I've noticed that I prefer is usually the setting in KDramas. They don't seem quite as urbanized. I like the smaller, warmer feeling I get when watching them. The first few CDramas I watched were all about living in a big, flashy city where everything is bright and shiny. It's not the same aesthetic.
