If it's a comparison between getting crap pay at McDonalds and getting crap pay in the hot sun all day, then there is no comparison.
Unless the work was picking onions or strawberries or some other crop which involves spending all day in a terrible bent-over posture. If the pay was the same, though, I'd rather spend the day harvesting apples than spend it making burgers for assholes.
Also, one nice aspect of getting humans out of the fields is that large numbers of human workers (at least) won't be exposed to pesticides.
The worst case is about the same. The average day is better picking fruit.
