Both the Reserve card and the AMEX Platinum give you some admission days. If you take advantage of the Reserve F Companion Pass, the card is essentially free. The AMEX Platinum includes PP and the other benefits that can also effectively pay for the card if you use them.

There are lots of caveats everywhere, including PP and spend on a card is tied to the number of Skyclub / Centurion Admissions. A lot also depends on which airports you use and what's available.
