Well, if the Mary Hunt who married John Smith in 1789 (somewhere in New England -- Tewksbury or Hillsborough?) actually was the daughter of Peter Hunt and Mary (Kimball) Hunt who was born in March 1758, then it would be best to use the profile that's now showing the "Nov 27 1758" as her profile.
But do you have evidence that I haven't seen for connecting this Mary Hunt to that John Smith? Her profile currently cites only the Tewksbury birth record and the Tewksbury marriage record. John Smith was born in New Hampshire and apparently lived there. Typically when a spouse was not from the same place where the marriage occurred, the geography is mentioned in the marriage record, so the omission of that detail makes me wonder. Are there wills, deeds, or other documents that connect this Mary (Hunt) Smith to the other members of the Hunt family in Tewksbury?
