Germany is usually at least in the top fifteen of that list, if not in the top ten. It's not as big as the US, but the disparity is substantially smaller than between the US and Denmark
I would be quite interested to see how they would rank the EU. Not an average of the EU countries, a score for the actual EU itself
There are ways to mitigate this. Scotland and Wales use a system that's basically FPTP with compensation. It's not perfectly proportional and some of the elected representatives are from a party list rather than being voted on individually, but the individual ones are picked first and it's proportional enough that voting for smaller parties isn't a waste of time
