I've already done it back in january of this year
The moderation staff doesn't take it too kindly when i post divisive yet TESTABLE/observable facts and opinions. Even if it's true, it's really not something (especially a TN owner) would want to hear, so out of empathy, i wil refrain from answering your question in a blunt manner.
but yes, i've already done it. And my performance suffered because i play a game where i need 100% clarity on my monitor, and the distortions of TN technology(since our eyeballs aren't falt, it's curved) and the saturation shift from top/bottom/corners/etc despite looking at the monitor directly in front of me are the main factors. this is game dependente however, i play rocket league so it's easier for me to know what the goalkeeper is doing on the TOP of my screen on an IPS than using a TN. On shooters, it's probably not a big deal.
Even if there was no saturation shifts and that there's no image distortation, the slightly added input lag will play a role in my performance. Not saying the omen x27/omen x25f have bad input lag, i believe rtings has the input lag equal to that of their most recently reviewed 240hz ips monitor, 27gn750 a slower 240hz IPS monitor
but when it comes to the 25" predator input lag or the 24.5" MSi input lag, these omens aren't as snappy. I tested the 27" version, which is basically just as fast as the fastest TN (x25f). 2.1 and 2.3 response times are basically nothing. For a point of reference, these are the FASTEST of the FAST, the top 99%(if not the fastest). There maybe unreviewed TN that maybe faster but generally speaking, the OMENs consistently get ranked the best in basically every reviewer website(along with the acer nitro xv253q
2019 taurus sho 0 60
when it comes to motion blur, i did'nt see any differences comparing my MSI to the omen in practice but the UFO tests are slightly better for the omen. then again, in practice i didn't see it. When ppl "whine" and complain as to why 240hz ips is so "blurry" it's bcuz they are probably comparing to much slower 240hz IPS. alienware/msi rarely gets compared to TN.(that reviewer compared all 3 of the alienwares he claimed that the aw2521HF as the fastest alienware(even faster than his TN alienware)
