This older quiz from the same source, covering the US, came up in a comment here the other day: https://www.nytimes.com/interactive/2014/upshot/dialect-quiz-map.html https://www.nytimes.com/interactive/2014/upshot/dialect-quiz...

So we don't get to compare, and it isn't sufficient to answer what you want - but it's interesting if you haven't seen it already.
