I'm not a competitive gamer but i do play games.
I was thinking that the monitor is a solid deal for a 144hz however it is a 2nd hand also a old model 2012/2013
Haven't really tried IPS monitor but everytime I read reviews, people said that ips beats TN display and this is brandnew.
I'm currently using a 19.5inch 1600x900 led monitor with VGA display
Modern TN panels are actually very capable compared to previous generations. Properly calibrated, you would be surprised how good a TN panel can look and perform. Yes, IPS does have some advantages, particularly in terms of viewing angles, but are they that far superior? IMHO, no.
When I settled on the Asus PG278Q, budget wasn't necessarily a consideration. I just didn't feel that IPS panels in the same category were that much better to justify the extra cost, and the fact that I found a good deal on the Asus just made it that much better.
If you can also get warranty support with a second hand one, that wouldn't be too shabby either.
