​​​​​​Things that make me value CSP:
-High SUB on CSP + additional referral points
-PYB program
-Ability to transfer to Hyatt, UA, United loyalty programs in case I need to top up for a redemption
-Reasonable AF



What Chase Ritz gives me:
-All the travel protection that CSR gives (car rental insurance, trip delay/interruption insurance even if you only charged $1 on card)
-Also gives a lot of travel perks that CSR gives including Priority Pass access to AUs. Unlike CSR there is no charge for an AU on Chase Ritz account. My immediate family members all have their PP for free through being an AU on my account
-Annual 50k Marriot cert
-$150 retention credit offered every year (I haven't ever had to pay the full $450 AF ever, YMMV)
-$300 airline incidental credit



What Amex Platinum gives:
-Centurion lounge access
-Other lounges like Delta (when flying with Delta), Escape, Lufthansa Lounges and more. I think Plaza Premium is leaving PP but will be accessible with Amex Platinum
-Various travel related incentives - one time $200 credit on Amex Travel portal, ongoing annual $200 airline incidental
-Generous retention credit
-FHR program
-Many Sync and ongoing offers like PayPal, Uber monthly reimbursements
-Some of these perks existed pre pandemic. Some are only for limited time till end of June or this year. A lot of them require some jumping through hoops, which I personally don't mind


I'm sure there's more but these are off the top of my head

Pardon for the format, am on mobile at the moment
