I'd go for the CG, no question (I have a newer CG246 btw). But I'm a photographer. The CGs are manufactured to extremely tight tolerances in all respects. In your case, however, reading, you might be better off with an EV2436 - not 2416 which has a TN panel (narrow viewing angles), but a 2436 with an IPS panel (wide viewing angles).
The EVs can be set to automatically adjust brightness after ambient light. This is a no-no for a photographer, where you would attempt to control the environment for a fixed monitor brightness, but for reading it might reduce eye strain.
An issue with newer LED monitors is pulse width modulation - IOW flicker. The EV2436 has no PWM until you reach extremely dim levels, so it should be safe.
