I just purchased a 12.9" to replace a 2021 11" IPP. The 5th gen 12.9" I never see in the refurb store, and with Veteran pricing, the difference between the older units on Amazon and Costco, and the new IPP 12.9 was $60. Figured the $60 was worth it to have a 2022 for resale or trade in the future. I would not make the move for any reason other than wanting the larger unit. The specs mean little. Not for what I do.
