AOC G2590FX vs LG 24GL650-B vs LG 24GL600F-B?

Read reviews displayninja on AOC and LG. Write that AOC is newer and better than the matrix and thus, better picture. In terms of speed, the AOS also seems to be a little better (but inaccurately). He is already through the Internet, bought AOC, but I really don't like his poor sight built-in on-screen, on video from YouTube he seemed thinner. Saw that LG just the point that, in fact I need. To change the scope, as I understand it, does not. If you put, that there are pitfalls: there will be a slight delay and it will be visible when recording video. So I thought maybe the Elk are generally not better than those LG? About them very laudatory write. If their in terms of speed to compare, which one is faster? And to judge by the reviews only one resource is somehow unreliable, I guess
