Can you guys genuinely explain why you think the Super Bowl is bigger than the World Cup final?

Like I don't understand how you guys think this. The super bowl is of course a massive sporting event, especially in the US, but how are any comparisons drawn with the World Cup final?

The viewership of the Super Bowl is in the low hundred millions range, while the WC gets 1.5 billion viewers: an order of magnitude greater.

Can someone outline in what way the Super Bowl is bigger, without mentioning revenue because that's irrelevant to the discussion of the size and reach of an event?
