The benefit of the heavy anti-glare is better glare reduction in bad lighting, as with strong fluorescent lighting. The reduced glare may also help with color accuracy so those who want to use this mostly for image editing are probably better off with a heavier coating.
This monitor also has less obstructive PWM flicker because it uses a CCFL backlight. LED backlit panels with PWM can cause eyestrain because LEDs turn on and off very quickly, without the more gradual glow that CCFL offers.
This monitor has an effective sRGB emulation mode, so it works for wide gamut and standard gamut uses.
