Agreed, but you don't need Sapphire Reserve to transfer, nor do you need Sapphire Reserve for insurance benefits, Sapphire Preferred is better value, especially if you need to transfer to more than one person's airline or hotel accounts.
That is actually something I've been contemplating is moving back down to the CSP. For now sticking with the CSR but could conceivably drop down to just 1 for the household. I need to run the numbers when my CSR card year ends to see whether the 1x extra on dining and travel offset the additional $60 in annual fee (which is all I view it as since I value the $300 travel credit at $300 cash since it covers travel that I already have planned as opposed to unnecessary travel spend).
As noted in the post above, 100k med evac is also a big one for me personally, and the Priority Pass is a nice perk though unnecessary as long as I hold the Citi Prestige.
