Ritz Card over CSR? Questions.

Just switched my old Marriott card for the Ritz-Carlton card through Chase.

My biggest perk use of the CSR was the Chase lounge/Priority lounge network. I’m based in PHL and travel often and theirs is pretty terrific.

For those who have done it - or similar - there’s really no need to keep the CSR any more, if my goal is the lounge access and Bonvoy point multipliers. Is that correct? Anything I’m missing? Especially with the rising cost of the CSR it feels like they’re priced out.

I’m also guessing since I have the Brilliant, that the days don’t stack and I reset to 25 days on January 1st annually.

Let me know thoughts and questions here. Looking forward to ditching a redundant card in the future.
