Our Verdict
AOC 24G15N
Samsung Odyssey G55C S27CG55
The Samsung Odyssey G55C S27CG55 and the AOC 24G15N are both low-cost gaming monitors. The Samsung is the better choice for most people, as it gets much brighter and has a more detailed display. However, both monitors have similar motion handling, so if you want to spend as little as possible, the AOC could work well if you don't need the Samsung's extra brightness or sharpness.
