I mean mathematically of course the 6 digit is better than the 4. But they bring up some good points about how humans artificially shrink the search space.
But what is vastly superior is going into the settings and enabling the alphanumeric longer pins (aka passphrase).
It's variable length and does not give any clues as to the length, and it allows for a much larger character set.
This vastly increases the search space. I don't even know how long my passphrase is (never counted), but it is long enough that my wife still can't remember it despite repeatedly telling her what it is.
Before the biometric unlocks I never used a pin because it was a pain, but now with the biometrics I so rarely need it that I think it's a great compromise.
