I would keep whichever card has the longer history and close the other unless there is a terrific retention bonus.
I opened both at the same time.
The PRG AF is a little easier to stomach and justify (only have to make up $95), if only because I don't use UBER and I don't fly as much these days to take advantage of the Platinum perks.
I'll at least have the metal card as a souvenir for when I get nostalgic.
