As a newcomer, which of the four types of romance novels is the best to write, the chairman's chapter, the crossing chapter, the Xianxia chapter and the rebirth chapter?

Presidential level. Need a little business knowledge. Crossing requires a little historical skill. Xianxia has a big imagination, but it is easy to be old-fashioned Rebirth, whether it is rebirth to ancient times, needs to know the combination of ancient and modern times and rebirth to modern times. It's easy, but it's also easy to be old-fashioned, and its theme is not easy to attract people. . .
