With the US and US hegemony, you can actually hold someone accountable. Bad actors can be protested, outed, and dealt with peacefully.
What I am not saying is the US acts with best interests of others in mind all the time - this isn't true either, and I'm not taking an extreme here on this, US has plenty of issues on the world stage (and as an American, at home too) - but centrally, we can be held accountable (and often are, esp. if you can get the US public opinion on your side).
You have zero recourse with China, if they decide to muscle into something, or support a horribly oppressive dictatorship to extract your national resources, there is zero - and I mean zero - way to appeal to any authority for intervention.
Yes, I'm perfectly aware we propped up dictatorships and overthrew governments, but I'm also aware of the fact that there were massive protests in the streets upon revelations of many doings that ultimately lead to them being undone or the US backing off, you have something of recourse there, you can deal with the US government in some discernible way you just can't with the CCP & Chinese government actors.
This has to be accounted for in the conversation when talking about international relations, especially when talking about "new hegemony" as it were.
I also question the assertion that the "world" has some massive distaste for the US. Unless world means China.
When Europe needs military assistance, who shows up?
When Australia, Taiwan, South Korea, New Zealand need assistance, who's right there, hands open?
Which nation has taken a very public and consistent stance against Russian military intervention in the Ukraine and committed billions of dollars in assistance without blinking?
I'll give you a hint: its not China
