Amex cards were once the clear winner in terms of rewards, perks and prestige. That hasn't been the case for several years. The SPG card discussed in the article--widely known as the most lucrative Amex--isn't nearly as valuable to me as, say, the newly introduced Chase Sapphire Reserve. Their flagship Platinum card used to be second to none for traveller perks. In the last decade Airline consolidation and competition with Airlines own co-branded cards has chipped away at the value of the Plat. You see things like amex being forced to build their own airport lounges, far from high-margin financial services..<p>That said, if you buy groceries for a family, I still haven't found a better card than their Blue Cash Preferred at 6% cashback.
