For me faster refresh rate is noticeable on phone or ipad where you scroll all the time. On a laptop you don't have that much smooth scrolling. For me it's a non issue on laptop, not even once I wished it had faster refresh. While I always notice when switching between Pro and non Pro iPad.
I find 60Hz on the non-Pro iPhone obnoxious since switching to 120Hz screens. On the other hand, I do not care much about 60Hz when it comes to computer screens. I think touch interfaces make low refresh rates much more noticeable.
No doomscrolling at all. Even when switching between home screens is like it's dropping frames left and right (it's not of course, but that's what it looks like coming from 120Hz). A Galaxy A54 that we still have in the house that was just over 300 Euro feels much smoother than my old iPhone 15 that cost close to 1000 Euro because it has a 120Hz screen.
Even 90Hz (like on some Pixels) is substantially better than the iPhone's 60Hz.
The Galaxy must be new. In my experience Android phones get extremely laggy [1] as they get old and the 120 Hz refresh won't save you :)
I just noticed that I don't really try to follow the screen when I scroll down HN, for example. Yes it's blurry but I seem not to care.
[1] Source: my Galaxy something phone that I keep on my desk for when I do Android development. It has no personal stuff on it, it's only used to test apps that I work on, and even that isn't my main job (nothing since early spring this year for example). It was very smooth when I bought it, now it takes 5+ seconds to start any application on it and they stutter.
