Why do you say mains 230V AC can be more dangerous than lightning?

Lightning is both more likely to be fatal and more likely to lead to serious injury.

Per exposure, you’re right that lightning is more likely to lead to serious injury and fatality. My claim was around the danger in the hand-to-hand mains case, where you can’t let go and exposure is sustained.

And more broadly, I wanted to point out that potential difference alone gives an indication about likely danger but (as with the electric fence vs mains) there’s more to the story.
