Speed? Both panels are practically identical except for the size and brightness:_)

That's why I got the Gigabyte Aorus FI32U....the size for 4k is brilliant. Big:)
The brightness varies between 40-60 %.....play in the basement, relatively dark. There is still more than enough reserve for bright rooms. 350 cd/m² is enough:)

The Asus is just a bit smaller....tick brighter......other than that, the two don't give each other much.

The Gigabyte doesn't have such a good input lag......30ms I saw in a review once....though I don't think that's very important for online gaming. You can forget about the 1ms response time anyway. Doesn't do any good.

I find the Gigabyte Aorus FI32U a top screen for the size and price.

It is driven by a Gigabyte Aorus rx 6900 xt Master. My recommendation:_))
