Of course it's not. But in some ways it is. China is totalitarian which the US isn't, and the US doesn't execute as many people, but still the US locks up a larger percentage of its population than China.
The US is better than China, but that's a low bar, and in a few areas it's only barely clearing that bar.
In other areas it's a lot better of course. Censorship is the big one. Also, the way China has oppressed some minorities (Uyghurs) hasn't happened in the US in decades (black people, native Americans). And the oppression did happen in a different way. But "different" isn't always better.
