Idk why people insist on the false dichotomy between commieblock and other types of buildings. Sure there are some truly awful ones, especially in Eastern Europe that are basically high-rise slums. But most of the insanely expensive and luxurious housing is also high-rise residential.
I've slept in a dozen kinds of them. Some are better than others, obviously, and even the worst of them were better than makeshift barracks or no housing at all. If they are built properly they are nice and affordable.
ed: Ask finns. IIRC they have a lot of these built right, with all their tech and a basic care about future homeowners, that is usually a flipping point in how livable commie blocks are.
