My eyes are not best-of-best but the difference between 60 and 120hz in something first-person is dramatic and obvious. It depends on the content but there are many such games for consoles. Your claim that it's "slight" is one that only gets repeated by people who haven't seen the difference.

Honestly, I can't even tell the difference between 30 and 60. Maybe I'm not playing the right games or something but I never notice framerate at all unless it's less than 10-20 or so.

I would guess it's partly the games you play not having a lot of fast motion and maybe partly that you're not really looking for it.
