There's a fair bit of nuance in this topic, but it can be argued that a totalitarian regime whose primary interest is remaining in power will resort to more oppressive measures towards its citizens than one that at least has some semblance of respecting human rights and democratic processes. This doesn't mean that there aren't things to praise and criticize about both sides, but _overall_ one system of government is demonstrably more benevolent, to its own citizens, at least.
What I'm really tired of, though, is everytime there's news about something worth criticizing about China, these comparisons with the West are mentioned. It only serves to muddle the conversation, which can be seen as the intent of whoever brings it up.
