@sammeciar Unless you can re-do that chart to include Visa's data from the ~2 years they were private while Mastercard was public (and as much as I love Koyfin, I'm pretty sure even they can't do that), I'd call that chart a bit disingenuous. Look at it from the day Visa went public and it's significantly closer (~1,500% for MA to ~1,400% for V).
That being said, I just prefer Visa, in my portfolio and in my wallet. Some metric for in Mastercard's favor, others go in Visa's favor. They're both great long-term holds. It's basically a duopoly with AmEx and Discover distant 3rd/4th.
Some anecdotal evidence: all the higher cash back (2-3%) and newer CCs I have are MA. I wonder what’s driving that and how it impacts the bottom line? Could just be a small sample coincidence.
