I have done a lot of looking into the difference between 240hz 1080p TN, 1440p 165/144hz TN/IPS, I found that there is VERY little difference between a TN and a IPS panel in terms of shuttering/motion blur. However the difference between 165/144hz to 240hz is way more impact than one may think. If you take a look at the high speed footage of 60hz vs 144hz/165hz vs 240hz its very clear how much less shuttering you get with 165hz/144hz vs 240hz. The human brain is used to seeing things in real time, 240hz is the closest to real time as you can get.
All of this being said, I personally will always go for hz over res, because hz of res will catch up and one day we will have a 4k 240hz screen, and when both the GPU's and CPU's catch up to screen tech, because from what I can see from current times of tech, screens will always be a head of CPU's and CPU's. The reason I will always be going for 240hz over res is because hz are like bandwidth, the more info your brain can get per second the faster your brain can react to it. Almost like ping not quite, just something to think on.
Another side note, the shuttering/motion blur between TN or IPS 165hz/144hz is so small that I would buy the IPS over TN. But a good IPS at that, so do your research into the IPS panel itself and not whos making it.
If your aim is the purest of pure visuals than sure a 144hz 4k would be epic, but faster info now is way more impactful than it looking good to me. I am a non-pro competitive gamer so response is everything for me.
