Maybe the Amex Platinum is the best card for your needs (pretty personal calculation that everyone has to make on their own though). I genuinely do not understand what that means in the context of this discussion. If there is less competition for your niche, what incentive does Amex have to target new updates toward you?

I would argue that the people that want a single card to elevate their entire travel experience to the next level would be best served by the Centurion though. I am not old enough to really understand what it meant to get an Amex Platinum back when it was invite-only. There are many data points for the Centurion invite (especially the Business Centurion) that show shockingly low spend requirements. I would be curious to know how exclusivity for the old Platinum (and even the OG centurion) compare to the Centurion today.

Regardless, it seems strictly better than the Platinum for people that are willing to pay an AF and do not want to coupon:

Better travel elite status:

Hilton Diamond, IHG Platinum, and Delta Platinum (!)

Better travel concierge

Better hotel preferred agent alternative (Centurion Hotel Program >>>>>>>>> FHR with $200-$300 property credits instead of just $100 and room upgrades on booking)

Strictly worse earning but I think it more than makes up for that with the 2cp/mr fixed value airfare redemption.

Not sure who has complained about the CSP changes (?) and, in my book, the types of people complaining about the CSR changes are the same people complaining about the Amex Platinum changes (people that won't use Lyft, DoorDash, Equinox, etc).

I think Amex and Chase know exactly what they are doing. However, the Amex Platinum definitely works for me whereas the CSR does not, even as someone that a) lives in Midtown Manhattan b) has a Peloton in his spare bedroom c) Lyfts and DoorDashes frequently. For my use case, Amex is strictly winning.
