OLED 1440P or 4K IPS

[JHONO]

I thinking of swapping my 4 year Dell S2721DGA, it's served my well as a gaming monitor. But I have the upgrade itch and have been thinking of going Oled 1440p or 4K IPS as these types of monitor cost around the same price and it's about what I paid for my current Dell monitor.

So what I'm asking, is what is the general consensus of which is better and what would you go for?

In the same boat with the same Dell monitor. Have the itch. Was looking at 4K but really love the 3 figure frame rates from 2560x1400p.

I believe there will be a fidelity increase still? There is also a slightly cheaper version of this that is standard OLED. The OPs monitor is QD LED. What's the difference here?
