Note that AEM shows a graph of this on their website (they call your attention away from that, but it is clear as day if you review the graph carefully) and even AFE points out that their oiled filter is superior for performance to the dry flow.
Unless you have filters utterly filled with gunk (i.e., off road or enduro racing), the oiled ones still win for flow with only marginally poorer dirt filtration.
As to the need for the marginally better filtration, unless you get a UOA that shows high sillicon (after break in is completed) or have a gunked MAF sensor, you can assume that it's working fine and take the better flowing one.

sorry man its all over thier website why AEM chooses DRY FLOW vs oiled on thier winning racing teams.
The Best Filtration AEM has reinvented the Lifetime performance aftermarket air filter. Our DRYFLOW Synthetic filter is the first performance air filter that does not require filter oil to filter and trap dirt and contaminants, and delivers industry leading filtration and durability that is unmatched by our competitors.
AEM’s DRYFLOW Synthetic filter eliminates the hassle of re-oiling after cleaning and has better filtration and dust trapping capabilities than any other performance aftermarket filter. AEM's unique non-woven polyester element filters out 98.6% of airborne dust in initial efficiency (99.4% cumulative efficiency), and filters down to ONE MICRON of particulate! For comparison, a human hair is about 100 microns thick.
This improved efficiency translates into longer engine life by keeping more ring- and seal-eating dirt out of your engine, with no degradation in engine power compared to our oiled air filters. taken direclty from thier website
