there are defintely 2 camps
after gaming be it competitively or casually for fun, those that do not bother about going 144hz or higher are generally "noobs" in the games that i play. no offence haha. but for FPS, refresh rate clearly is very important not only for people who are going pro but for just individual satisfaction.
Try it first and see for your own.
going to 144hz is not only about a competitive advantage.
Even for normal desktop usage, be it browsing, moving up your web page up and down has smoother feel and look since more frames are shown on screen. 60hz at this age, is really just for office use or someone who doesnt game at all. For a home entertainment system, with how good cpu processors and graphic cards are, why bottleneck your system with a 60hz display showing out 60 frames only? Games in this generation hardware evolution clearly can show more than 60 frames in most games.
its like people spending money on multi core processors like ryzen and intel i7 etc, fast SSDs and modern graphic cards, but end up the display where you are show casing what your hardware is, is a slow choppy 60hz monitor. Spend so much for your hardware and the final user experience on a display is choppy. O_O
Of course those who are using a 60hz monitor up till today will argue that 60hz is fine, of course its fine because you didnt experience 144hz yet. Some dont wanna get 144hz because..... .... they wanna save money.
In regards to eye strain, get those 144hz monitors that is Flicker free or have low blue light emissions.
