One scenario where I notice a big difference is when I read text while scrolling, like reading this forum while constantly slowly scrolling.
I have a 60HZ screen next to a 144 Hz Gsync monitor and the last one is usable and the other clips and stutters to much to be able to read the text. But I think in this specific scenario 240 and 300 Hz also would be noticeably better.
In games I think Gsync did more for me than 144Hz, but I can't complain about having higher refresh rate even though I'm not sure I would notice going from 96 to 144Hz
