The X-ray's false-positive rate is considerably lower than the EDS CT machines.
I'm not sure what you mean by "quickly clear large quantities of checked bags" when the false-positive rate has been shown to be 30+% and the false-negative rate is unknown.

The Xray can show organic material in a different color but there are lots of things, other than explosives, that will show up as organic.
The new checked bag screening machines are the best technology we currently have available. They do what no other current technology can do which is to quickly clear large quantities of checked bags which greatly reduces the number of bags which need additional attention.
