For sure, there are! You can't publicly complain about the government in China, and as much as Trump is thin-skinned, his reactions to criticisms aren't to the level of the CCP. Their economic and political model is also so top-heavy, if the president is a mad king, the impacts will be much worse, much faster, than a mad king in the White House. There's a lot of risk there.
As for showing every sign of going to be worse... I don't know. I think that's where western propaganda is working extremely well, people have this perception that the CCP is evil. The CCP is dictatorial, but historically has brought hundreds of millions of people out of poverty. I'm sure there's corruption in the ranks, but we have that too (if you can straight up say 100% of US politicians aren't corrupt... you're either very good at lying or deluded). However, when I look at the results, their government has been a net positive for China. Yes they have horrible treatment of some ethnic groups, yes they're controlling in a way no western country is, but if you take an utilitarian perspective, they've done well for their people, generally speaking.
Will a Chinese hegemony be worse for the world? Maybe. I can see them adopting a harder stance than the US on many things. On the flip side, the US has undermined foreign governments and started wars for self-serving purposes, multiple times. The propaganda keeps painting China as a belligerent entity, but I'm not sure they're that much worse.
