This thread should've ended after the CSR recommendation. Best signup offer ever.
At the time of the OP, the 100K was no longer the signup offer....so, yes the thread should have gone on because there was room for debate.
50,000 points equal to $750 in travel redemption, $300 travel reimbursement, free TSA Precheck/Global Entry ($100 value), among other benefits, less $450 fee. But hey, I don't want to get in the way of your referral links to inferior cards.
CSP has the same Ultimate Rewards sign-up bonus with no Annual Fee in the first year, $95 after that. The "travel redemption" piece only makes sense if you use the Ultimate Rewards to book travel...but URs are worth more when transferring them to travel partners.
So, pay $0 hit min. spend and get 50k URs.
CSR - pay $450, hit min. spend get 50k URs get $300 in travel credit and access to TSA Precheck (who cares?). You're paying $150 with the CSR and if TSA Precheck is a must for you, you're still out of pocket $50 more than with a CSP.
If you are only applying to get the most URs for the minimal cost (and don't care about Priority Pass or TSA Precheck) then CSP > CSR.
Also, thank you for your conceited dig. I applied for the CSP and a few weeks before getting ready to apply for the CSR, Chase came out with their new "family rules" on the Sapphire cards.
As an fyi, they are data points out there of people double applying for the CSP and CSR on the same day and getting both bonuses. If you can handle $8k spending in 3 months, 100K URs could be yours.
