What's the difference in structure, function and use
between the Spacehab and the MPLM?

The Spacehab is designed to stay in the shuttle payload bay, has extensive
power capabilities to run internal payloads, and has a small tunnel leading
to the ODS.

The MPLM is designed to be berthed to ISS, has more limited capability to
power internal payloads, and has a large square hatch leading to ISS.

Thanks. So why the Spacehab this flight, when the MPLM
in the past?
