Airaid is better choice
Between the two, Airaid is the better choice for sure. As another post noted, a Cold Air Intake should draw air from outside the engine bay. Many do not. Airaid does. BTW, so does the stock airbox. You may consider just dropping a K&N filter into the stock airbox, Ford did a good job of designing this one. If you still want a more custom look, you can replace the airtube with one from Airaid that flows a bit better than the stock one and looks much nicer for a lot less than the full CAI kit. Just my $.02.
