Help in choosing to live in Maputo or Nairobi

I have been asked to take a director's position with an international development organisation and have been given the choice of Maputo or Nairobi in which to make my home.  After a very brief visit to Maputo my fiancee is not very excited about being left there alone while I travel. 

She is a financial controller for a highly successful agricultural firm in Washington State--an accountant who likes to fix systems and solve problems.  She would also be looking for employment...which means she would likely need to drive herself to work.  The Maputo traffic is another reason she is not too excited about going there. 

Of course a few more days or weeks are really necessary to gauge what it is like to live somewhere, but we had less than 48 hours to see Maputo and will not be able to visit Nairobi at all.

Can anyone give us any informed (on the ground) input to compare the living conditions in these two cities?  Also, any leads for possible employment for her would be appreciated.
