I could believe you feel less latency, but suspect that’s more a symptom of matrix scanning working for the general case rather than being optimised for your layout. Scan with an RP2040’s PIO [1] and after debouncing I’d challenge you to measure the difference, much less notice it.
(Of course if you’ve got the pins, you should use ‘em!)
