Do you have specific requirements? Like refresh rate, motion blur reduction, brightness, color volume, ergonomics, connectivity, etc. ?

Both monitors are fine for your use but based on the reviews, the AOC may be slightly better than the LG.

If you don't mind to spend a bit more, look at the HP Omen 25i. It has very good out-of-the-box color and higher color gamut. higher refresh rate as well so it is good for both artwork and gaming. this monitor is a bit underappreciated I think, solely due to its price (rm1k) compared to its competitors.
