For me it's not so much what's interesting as what affects my day to day. I love Chinese history but I'm unlikely to come across anything today with origins in Chinese law, or traverse the path of a Chinese road, or use an interesting word with a Chinese etymology and an associated story from old China.
For national history, Chinese is probably my favorite by far.
May I suggest you do a domain-specific history dive, such as the history of computing, the history of science or some other subject you may enjoy more. That's the real good stuff.
