I think there are three groups of people with opinions regarding 120Hz vs 60Hz refresh rate.
Group 1 can tell the difference between the two and strongly prefers 120Hz.
Group 2 can't tell the difference between the two and prefers the more affordable options.
Group 3 has not done a lot of comparisons between the two refresh rates, or has used 120Hz displays that were actually in 60Hz mode, or compared lower resolution 120Hz displays with higher resolution 60Hz displays.
I think a lot of people mistakenly think they are in Group 2 when they are in Group 3.
