Microwave oven venting options

I am about to mount a GE Advantium microwave under a wall cabinet over a range. The two venting options are through the cabinet, ceiling, attic, and out the roof; or through the internal microwave filters into the kitchen. Because this model is high-end, I'm assuming the venting capacity and ability to filter grease and odors is good. However, my assumption (right or wrong) is that venting through the roof is a more efficient solution. Given the much more difficult task of installing external venting (I would do this myself), I wonder if on balance the external venting is worth the time, effort, and cost. Any comments?
