Kdramas are really available and easy to get. Their quality is much better and well, their dudes xD. Sadly, the stories are not that different from each other and the main characters tend to have the same personality. After years of watching dramas I still prefer Jdramas because they have more variety in almost everything, and they tend to be more creative. I'm also so familiarized with the actors that sometimes I watch a jdrama cuz I know all the actors and it's more fun that way. In korean dramas I get tired at, exactly, the 12 episode, idkw the story just takes a different direction and sometimes not for the best. Also they are very popular for their romance (again not much difference between stories) and since the japanese don't have many romantic comedies, and also their romance is kinda hard to get for us in the Occident, well they are left behind.
Anyways welcome and I hope you stick to our jdorama side ;)!!!!!
