Which 3ds should I keep?

I have both the Pikachu New 3DS XL and the Link Between Worlds OG 3DS XL and have a hard time choosing which one to keep for purpose of rarity and holding value in the future. I already have the SNES and Fire Emblem one and want to just have one more in the collection.

Which of these two are more rare and desirable you think? I really like both, the Zelda 3DS XL is by far (for me) the best looking OG model with the gold metallic which is really unique instead of just black inside. Same goes for the Pikachu version having the yellow throughout. Really torn! To lastly note, pikachu is japanese version and zelda is PAL.
