IMO I think either of your choices are too small for food use and I don't understand why you have narrowed your choice down to these two folders. Fixed blade knives are easier to clean and maintain for food use and less likely to harbor bacteria (harder for the critters to hide). You don't say whether you plan food prep or strictly table use. Does it need to be portable? Do you want serrated for lower maintainance sharpness or for some other specific reason.
Other choices that come to my mind include 4" Utility, Vagabond, Temperance, Stretch, Endura, Police, Pacific. Of these, Endura, Vagabond and Utility are well within the price range of your choices.
If it is either Native or Delica, I'd go with the Delica.
