My laptop uses a 144Hz Gsync VA panel (3ms from memory), ASUS ROG Strix GL703GS SCAR 17.3". It's not convinced me to upgrade my 60Hz 1440p IPS panel yet, though no doubt my next panel will be faster. I don't notice the difference when gaming unless I jerk the mouse around, which I don't do. I prefer relaxed gaming, maybe with a nice malt whisky
I think the sad thing is people feel they need higher FPS to be competitive within online games. The industry drives this opinion to sell new hardware. Me, I'll take quality over quantity when given the choice. I'll even cap FPS/undervolt to keep things running cool and quiet.
