The ones build in Soviet times are better because the big cities weren't yet that huge so those "sleeper districts" build on the outskirts of the city are much closer to city center than the ones that are currently being built. Also the soviets baked more infrastructure into them, but I suspect much of it has been sold to the highest bidder after the Fall.
Also the ones that were supposed to be temporary are called Khrushchevkas and are up to five stories tall. Most taller ones build after were supposed to stay.
I'm talking about Post-Soviet ones.
