Not a fan of ziq but I do have to admit that I’d agree that marxism and anarchism want something different. I think it’s fair to say they want something similar but not exactly the same. Marxism wants communism that is supported through a marxist like apparatus, with a centralized administration, even after the withering away of the state. And they would still support heighachy and the existence of political power, while anarchists who advocate communism advocate for a decentralized anarchist society with communist economics
