Just an aside, but Delta SWUs have been discontinued for Delta Platinums in 2014, it's really an enhancement.
Diamonds will have a choice of Global Upgrades, for international travel; but there is no equivalent for Platinum Medallions.
Also, don't really get the "eye-candy" aspect, as I never get a chance to hand my AMEX to anyone (when paying chip+PIN), with exception to checking into a hotel. So, that benefit, seems to be squarely US focused.
