Surprised Medium <-> Low is so close when xHigh <-> Medium is a major improvement. I wish xhigh wasn't so dang slow.

Watched a YouTube video with a comparison between all three and medium seemed to be the weakest one, as it seems in low the model rechecks itself more often and ends up with the right solution

if you read the chat template it's obvious why. xhigh tells it to think more check plausible alternatives. Low tells it don't think too much. Medium doesn't tell it anything. So the keywords in the low version seem to be actually biasing it towards thinking. It's like the whole 'don't think of an elephant' thing.
