I'd say that determining exactly what makes mice or monitors feel different is not measurable with feeling, but we can definitely feel when something is "off" from what we're used to.
I tested the AB lag test some months ago and did get some low values to. But I remember there's some things to tune before do a proper testing.
Also, I'm not sure how stable is the frametimes. Maybe when the cursor change sides it generates microstuttering or something, and people misinterpret this behaviour as input lag. I would love to test this myself but I lack a high speed camera. But blurbusters is a very good source to reliable information about display lag.
People need to remember the "input lag" have a quite large path, maybe the bottleneck is in one source and people keep blaming another source.
Sensor feeling is a very different story, float sensor not necessarily have something to do with inputlag. Basically any disconnected movement you feel could be named as "input lag", and even so, we just get used to some different technologies, even with their flaws. I remember reading this article saying how PTE sensors are more "precise" in a lot of ways: https://www.hindawi.com/journals/js/2016/4281397/
but a lot of people just hate playing with then, even on hard pads who reduces greatly the positive acceleration. Go figure.
