I mean it depends on what you like.
For one, Chinese drama is wayyy longer than kdrama. Atleast double of it. So if you're the type who like long drama you'll love Chinese drama. With the longer duration, they able to dwell and develop the character better (although some just feel like dragging)
The genre that I watch for Korean and Chinese drama are also different. For korean drama, I mainly watch for their crime, mystery and detective genre. For Chinese drama, I like to watch the emperor-dynasty kind of drama. What they so called wuxia and xian xia drama. Example of my fav Chinese drama includes the untamed, nirvana in FIRE, and the sleuth of ming dynasty.
So every drama has its own pros and cons. And I love both of them :) well.. I watched all sort of dramas tho, from thai, Japan, Korea and chinese~ and each of them for different genre :)
