PG27AQ vs. PG348Q (What has better image quality) or an overall better experience

[tnance24]

Im looking to upgrade my ROG swift 1440p 144hz monitor to a 4k monitor. But I am confused on how much better the image quality will be with the 16:9 vs the 21:9 ratio. I assume the PG27AQ will be higher image quality but only 60hz. But i just didnt know how much better it would look compared to the wider monitor. I am going to have 2 1080's by the way. Please help

The PG27AQ is a little faster 1-2 ms faster response time but the PG348Q has a much better delta profile... Also the AH-IPS PG348Q is a much better panel than the PG27AQ..
