Excellent summary!

I've been considering a switch and this was good info to have.

I do want to clarify the Amex Plat Fine Hotels and Resorts (FHR) program however, because I do feel that it is one of the better benefits of the card, IF you use it. The FHR program basically gives you:

--A space available room upgrade
--Complimentary continental breakfast for 2
--Guaranteed late checkout (to 4 PM)
--One additional amenity depending on the property (usually things like a spa credit, a free dinner for 2, welcome basket, etc.)

You have to book with PTS at an FHR property at the FHR rate--sometimes not the cheapest, but very often worth it when considering the benefits, like the upgrade and late checkout.
