Can your computer handle 1440p? If it can, its all about personal preference. Personally i like 1080p monitors more, but i know some people who would prefer a 1440p monitor.
They are both g-sync 144hz monitors. What about 1440p 144hz ips, is it worth $450 more?
To me tn looks meh compared to IPS/PLS and i would take IPS anyday which also works for photoshop and video editing as well. But mainly whats your specs because its going to take some power to run 1440p and 144Hz
But what monitors you looking at for it to be 450 bucks more
