The CFM info for the Papst 6424H on that page is not correct, it's a 280CFM fan.
Here's the data sheet

Looking at the data sheets it seems like the papst handles backpressure a little better, the Comair is probably quieter. How they'll work in your application though is just sort of guessing. At $14-$15 you might as well buy one of each and see how they work for you. They're both fun ;-)

If you really want to get a 12V version you can buy them retail, but they're expensive. The papst runs about $100. Here's some links for retail fans
