When the fuck did I say they were worse than the evil empire? It's definitely a better place to live for most people right now, but that's mostly incidental. Just like whenever the US or USSR were better in one context or another, empires can support themselves in good and bad ways. Fascist states are typically all bad, where liberal and Marxist spouting empires tend to have both genuinely redeeming qualities and broken ideals to their name.
There are no good empires, and the second you buy into one being fundamentally different you've eaten the propaganda. Many Marxists forget how imperialism is an evil that far predates capitalism, an evil necessary for allowing capitalism in the first place. Thinking that evil will meaningfully destroy capitalism is the greatest con imperialism ever pulled. Even the empires that actually rejected capitalism in the 20th century were big fans of genocide, violent repression, and cults of personality. Now those empires are all fascist or neoliberal.
The Soviet Union was functionally a Russian empire. It centralized power around its imperial core, refusing to exist in a coequal federation with the other member states. It's why it fell apart and why Putin sees its collapse as such a tragedy.
China is imperialist without even considering Taiwan. They violate the sovereignty of all their neighbors in the same ways Chinese empires have done historically. They embrace social conservatism in their moves to take rights from women and suppress queer people. They play into nationalism more every year, not because they're a smol beans, but because they're embracing increasingly fascist strategies with the rest of the world. It doesn't make them unique, it makes them no different from the rest.
Assuming ideology trumps geopolitical "realism" is naive. Ideology is a inconvenient but necessary tool for building power in hierarchical systems.
