I get value out of both in separate ways that save me more than the annual fee, for every year i get 300 in travel credit on CSR, my amex I get $200 in travel credit from specific airlines, last week i bought $200 in american airlines gift cards, this week i will buy 200 more thats free flights. I get free urber credit with my amex monthly so this is a benefits, I get $100 saks credit with boths cards so use those.
Amex lounge access give me access to hundreds more lounges. I get special event perks with both cards, my CSR gives me 3x dining credit, amex 5x travel credit but like i said I dont use this for travel because amex still has less hotel options and no 50% bonus booking.
CSR also has much more travel airline partners where you can redeem 1to 1 miles. I got about $6000 worth of travel out of these cards so it offsets the $450 and $550 annual fee on them. the yearly travel credits alone almost surpass them... hope this helps
oh the CSR card is a better cards, it has been the top premium card since it came out..
but as a status symbol Amex Platinum, pull it out and people automatically assume you are doing well because it has been the prestigious cards for decades...so it will get you some a$$ easier once these thots see it lol
