Indeed, let's hope the US succeeds against China. They're both evils, but the US seems to be the lesser one.
If the United States succeeds and wins against China, it means we will continue to maintain a unipolar world with the dominance of a single power. This also means that we will continue to be bullied and threatened by them without being able to fight back or resist.
Meanwhile, if China succeeds, we will have a multipolar world with power evenly distributed and no longer concentrated in one country, including China.
Both are bad guys and the best scenario for the world is for them to compete with each other, power should be divided rather than concentrated entirely in the hands of one of them.
