I can only say I've been to a few cities here and there and nowhere did I feel as overwhelmed by the scale as in Moscow. Many of the cities remained not that high, London or Paris do not have such buildings in their city centers.
> That Paris thing is certainly bad, but it looks rather like a backside
I live in Paris; believe me, the best and the worst are two streets away. There are quarters in the 18th or the 13th that make OPs photo look like a dream.
Now there is a lot of subjectivity here, and to be honest, I'm not fond of the Warsaw building either, so I might be a very poor judge of modern architecture.
