I think it's pretty clear that China is nothing like US. I think it's important to look where the labor and resources are allocated in the country. In a capitalist state like US, they're primarily allocated towards producing surplus value for the capital owners, meanwhile production of socially useful things is entirely incidental.

On the other hand in China, we see huge amounts of resources devoted towards ending poverty. They are on track to eliminate abject poverty this year. They poured more concrete in three years than US has in the entire 20th century. They provide food, housing, healthcare, and education for the vast majority of the population.

China also hasn't shown aggressive imperialist tendencies like US. Since the 1970s, China has not once gone to war while US has not spent a day at peace. Since 2001, the U.S. has spent over $6 trillion on military operations and war, money that might have been invested in the infrastructure of home.. So, while capitalism drives constant war and exploitation, socialism is improving the quality of life for the people of the nation.

Furthermore, CCP has 90 million members. This comes out to 15.5 citizens to every party member. Xi has also introduced reforms that make membership more strict in order to prevent careerism. So, every person in China either personally knows a party member or related to a party member. This translates to China having strong social programs, providing housing, education, and healthcare for their citizens that I mentioned above. People in China predominantly agree that the party is working in their interest.

China now surpassed US in number of fortune 500 companies, and 24 out of the 25 largest companies in China are state owned.The only private company on there is Huawei which is technically a cooperative. China also keeps their billionaires on a leash, and actually jails them which is unheard of in the West.

It's also worth remembering that China is working towards communism. Nobody is saying that the current situation is the end state. Both Marx and Lenin say that you can't just create a communist society out of the blue. It has to be a process to transform it gradually towards communism. This is the whole idea behind withering of the state. Lenin also correctly notes that it's not possible for this to happen until communism is the dominant ideology in the world. The capitalist forces are always going to fight communism, and a state is needed to combat that.

China obviously has made mistakes, but that's just how life works. It's not possible to do something completely new and get everything right on the first try. However, what's important is that China is clearly learning from their mistakes and improving as they go along. This is in line with the concept of implementing scientific communism.
