The interior packing area of the U166 and the Crew9 are about the same, with the interior of the Crew 9 being maybe a tiny bit larger - if at all. However, I find that packing the U116 feels a lot easier, since it zips open to allow top and/or front loading, whereas the Crew 9 only allows front loading. That may simply be up to individual preference, but top loading feels easier to me. Being able to get something OUT of the bag while in transit - like an electronic gadget - is CERTAINLY easier from the top (like the U116), rather than from the front (like the Crew 9).

Hope that helps.
