If your phone is choppy when scrolling a list on a 60 Hz display, it's not going to scroll smoothly on a 120Hz display.
My pixel lets me pick between 60 or 120Hz refresh rate, the bump in perceived smoothness is substantial, to the point that 60Hz does appear choppy in comparison.
iOS at 60Hz is so much worse than Android at 60Hz, I don't know why. maybe Apple did it intentionally to sell more iphones
Phones today have plenty of power to generate 120 screens per seconds. Capping them with a screen is a terrible idea. Smooth form a decade ago isn't the same as smooth of today.
20 years ago I was gaming at 30fps and called it smooth. Now 120Hz feels like bare minimum.

It will be buttery smooth between the chops.
