Ultrawide monitor: flat vs curved?

I'm in the market for a new monitor and I wanted to get a ultrawide, I almost exclusively play videogames on my PC. I found some good candidates, but because of price I'm heavily leaning towards a flat panel instead of a curved one, namely AOC U34G3X.

Is a flat ultrawide panel much worse than a curved one for gaming? I've used flat panels since they started selling it, but the longer diagonal scares me a bit. I'm currently using a 27" flat panel.

Thanks in advance for any and all suggestions!
