I have libby's with each of the weapons in question and the Axe or Staff has my vote every time (in that order). The staff being AP4 can be....frustrating...against T/MEQ. Considering you face 'Nids and Guard most the staff would likely be sufficient.
For fun you could always go Force Axe and Mace of Redemption and pick whichever one you need to use at the time.
