I would recommend going with the ASUS TUF option, due to sRGB: 120%, but I would also consider Xiaomi curved gaming monitor 34" if you are willing to spend extra $$$.
Despite your final choice, all monitors are good and if you are not an expert in this area you won't spot a huge difference between them, so you can also go for the cheapest option, and spend saved money on something else
If you never had an ultrawide monitor, you also need to keep in mind that some games like Elden Ring do not support a 21:9 ratio and the ultrawide community is still not that much important for developers. Hopefully, this will change shortly!
