i used an android phone for a year with a 90 fps display. When I switched back to an iphone, it felt slow to me. i couldn't tell what the problem was, the brand new phone just felt sluggish. a year later when using my partners iphone pro, i realised that the sluggishness must be because of the refresh rate.

i think once you get used to 90 or 120 fps, then 60fps will just feel choppy. no need to compare them side by side.
