I think the trick is to have many holes in the media and all the holes be consistent in sizes. Say you have a lot of media but less pores and some pores are big and some are really small, you might end up with the same efficiency but your flow will suck despite having more media area.
I think efficiency, flow, and holding capacity are more imporant measures than just media size. They can probably put more cheap media cheaper than a little less good media. But of course all else being equal more media is better, but usually more media means better flow and higher holding capacity. The P1 seems to do well on all accounts.
