The bigger the screen, the more you notice because it covers more of your field of view. I would say 240Hz is the sweet spot. You can definitely feel the improvement from lower rates, but rates above it start to be barely noticeable. However I am fine with 144-165Hz if I wanted to save money and still get a great experience. Bellow 120Hz is unusable for me. Once you go high refresh, you cannot go back, ever. 60Hz feels like a slideshow. For gaming 60 is fine, but for work use and scrolling around I can't have 60. Yes people, high refresh rate is useful even outside of gaming.

Funny thing is, while gaming, even if my monitor and PC can do it, I rarely let my fps go above 120-140. I limit them in the game. PC gets much quieter, uses less power, heats up less and its smooth enough to enjoy a great gameplay. I will never understand people who get a 4090 and play with unlocked fps just to get 2000 fps on minecraft while their pc is screaming for air. Limit your fps at least to your Hz people, have some care for your hardware. I know you get less input lag but you are not Shroud, those less 0.000001ms of input lag will not make a difference.
