Oyster Perpetual vs. Datejust

[Mattomatic]

Hi folks,

I've been racking my brain (Bordering on obsessive) and have come to the conclusion that I want... no, I NEED to pull the trigger on one of the following: New Oyster Perpetual Black Dial OR Datejust - both in 36mm and configured exactly as the images below. As I'm getting older I appreciate a smaller watch on the wrist.

Here's the tricky part, something from my collection needs to go to make room (See my 4 current watches in the signature below). Adding a 5th is NOT an option, so you're not allowed to make that suggestion

Which would you add, and which would you kick to the curb to make room??

Thanks for your insight!
