> the PRC is more competent in every way

I guess it depends what you mean by competent. Dictatorships can be frightfully competent at certain things, but that doesn't make them a good place to be. We're talking about a country that is genociding its own Uyghur ethnic group, represses Tibetan culture, disappears its own elite athletes, and has a horrific LGBTI record. The US is far from perfect, but has nothing on China in terms of nastiness.

That's not even touching the biggest problem of dictatorship, which is what happens when Dear Leader takes a fall. I doubt Xi has much more than a decade of leadership in him, and I worry for the Chinese populace when he goes.
