I lived through Communist Poland.
Comfortable life for officials meant that they could use stores with stuff from the west (to buy Levi's jeans, Marlboro cigarettes, or perhaps even a walkman - you can google Pewex to read about these stores). Many of them had also homes. Not as in villas, but as in plain homes that you see in american suburbs.
One of the country leaders in 1950s built himself a villa once, but he never got to live in it, because the rest of the leaders make it understandable to him that it will end badly. So he ended in one of the regular homes. (you can google Ochabówka - I've been inside, and again - it's like twice as big as a regular american home, nothing like a villa you would imagine).
You can also google how Gorbachev and other Soviet party leaders were living. It was better than common people but not much.
The main difference in quality of life was that the regular police couldn't just lock you up (secret police could though), and you wouldn't be beaten up by simply showing on a street during work hours, or doing some other crazy stuff like wearing colorful socks or long hair. I mean, no party official would dare to do it anyway, but regular police wouldn't stop them.
So on one hand - yeah, the societal divide was way lower. But it meant nobody was free and everybody was poor - as in no TVs, no meat, and even a toilet paper was a luxury. Nobody I know would want to get back to that.
