Not a fan of censorship here, but Chinese models are (subjectively) less propagandized than US models. If you ask US models about China, for instance, they'll tend towards the antagonistic perspective favored by US media. Chinese models typically seem to take a more moderate, considered tone when discussing similar subjects. US models also suffer from safety-based censorship, especially blatant when "safety" involves protection of corporate resources (eg. not helping the user to download YouTube videos).
