Well they're two very different panels. Gaming will look much better on the LG panel as it is 'Ultra wide' and IPS, however it will perform much better on the BenQ panel as it is Tn which yields 144hz refresh rate an 1MS response time. It all comes down to preference really. Do you want the game to look more aesthetically pleasing or appear smoother? personally I'd have to say if you aren't playing your games competitively, the LG platform would be a better choice. As I said, it comes down to personal preference.
