I have it on my Samsung S21 Ultra and I really don’t see the craze for it. I turn it off because I’d rather have the battery last longer. I might feel differently if I did a lot of gaming on my Samsung. I used to, but I prefer playing games on my Switch. I play simple puzzle games on phones and those don’t need fast refresh rates.
But everyone’s vision is different so i believe people when they say it means a lot to them. It just doesn’t, for me.
