Yeah... No! I don't have an axe to grind here but indeed there are more than one way to compare a product.

Air debit is only one dimension. You can pick arbitrary dimensions to compare products depending on which one you want to (if you would) show preference to.

Did they check also the noise level? The dimensions? How long you can run the thing before changing the filters? Do they have some form of regulator or are they always on? Do they fall apart when you bump on them?

It's like comparing processors by their clock speed. Which one 'is outperformed' by the other?
