No need for name calling. I have a masters in mechanical engineering and am working on a cryogenic space radiator for work. Its being pretty semantic to say “well ac-tually 127C is way above room temperature, so this article is invalid and the breakthrough is irrelevant.” My point is that a significantly smaller system can be produced to run at 127C that’s normal industrial equipment and some hotter electrical equipment levels that doesn’t require a large power helium cryocooler system to run continuously, like many devices that use superconductors today need.
In that case I would say take a look at the US Bank Attitude reserve if you are able to pay with mobile wallet.
Its really going to depend on your spending profile to determine which is better though the CSP and CSR target people who eat out and travel more.
Do you fly when you go on your 1 trip or drive? Another option would be to get one of the hotel cards. The Ritz Carlton card is basically a supercharged Marriott card with many of the same benefits as the CSR.
