I apologize if this is in the wrong thread, but I need some advice with an upcoming booking for the Hilton Barcelona(greater than $250 total)

I'm a Hilton Diamond because of the Aspire Amex. I have the following cards with the associated promos that I'm aware of at the moment:

Hilton Aspire Amex

Amex Platinum: Spend $250, get 5,000 MR

Amex Everyday Preferred: Spend $250, get $50 back

Which card would you use?

Thank you for any feedback.
