I run the Fujita CAI which is similar to the DC. The sound is nice, the pull is nice, and the look is nice. Against the AEM though i highly doubt theres a gap between their performance when it comes to their installation construction. Unless there was a highly detailed comparison with performance figures, then you would decide closely. As for the filter, most of them nowadays are washable. I ditched my Fujita filter for the better built AEM Dryflow. And TBH, i think the filter makes a big difference.
