Recently my wife decided to go back to work.  Since the birth of our daughter (19 months ago) she's been a stay at home mom.  It has been a blessing for her to be there, but it's just not practical at this point.  Unfortunately, we don't have the funds to be able to enroll our little princess in day care just yet.  To raise the money we need to make the transition from a one income household to a two income house, my lovely bride has become part of the "gig economy."

Currently, she is working for Postmates and she just signed up for Door Dash.  She is also considering Waitr, but the concept is the same.  She can "clock in" whenever she's ready, and "clock out" when she's ready to quit.  She gets paid per job, and we can fit it in whenever our crazy schedule allows.  Make no mistake, she's in it for the money - so, in that regard, the question is: Which one is best?

For the purposes of this discussion, we are excluding restaurants that do their own delivery.  We are focusing on "gig" type, work when you want services.
