Lightboost turns down the backlight between frames.
It causes reduced brightness and flickering, which some people don't notice and others find unbearable.
Lightboost was designed to be used with 3D glasses, but can be enabled without enabling 3D.
Both of these are gaming monitors with pretty ordinary image quality. Their selling point is reduced latency and image blur. To really take advantage of them you need to be producing well over 80 FPS.
The Asus PB278Q you mentioned earlier is a completely different beast. This is an IPS panel with much better image quality and higher resolution but more image blur and higher latency. How much these matter depends on what you use it for. Fast monitors are best for twitch games where you have to react very quickly. For anything else, the IPS panel is better.
An alternative to the Asus PB278Q is the Dell U2713HM. This is a similar panel which is slightly slower but has better uniformance and color accuracy. The image quality is fantastic.
Trying to fill the gap between gaming monitors and these IPS monitors is the Asus ROG PG278Q. This has the very fast reaction times of the gaming monitors but with higher resolution and image quality. It is still a TN panel, so viewing angles aren't great and panel uniformity is not as good as the IPS monitors mentioned. Color accuracy out of the box though is great. This monitor has only a single displayport input.
My recommendations:
If you have a very fast computer and play mostly games like Battlefield or Counter Strike, choose the Asus ROG PG278Q.
If you play slower paced games or use the monitor for more general use, choose the Asus PB278Q or Dell U2713HM.
I also see you are kind of fixed on the 27 Inche with higher resolution. I know the BenQ I mentioned is 27" but only 1080p.. but it still got many awards.
I am not so sure about going to higher resolutions, since it is still quite demanding.
You had listed a mix of 24" and 27" monitors, so I made suggestions of 27" monitors.
1920x1080 resolution is low for a 27" monitor. At this size, I would recommend a 2560x1440 monitor.
1920x1080 is fine for a 24" monitor.
The BenQ XL2720Z and Asus VG248QE both use PWM to dim the backlight. If you have sensitive eyes, don't choose these. The Asus PB278Q is the same. You also want to stay away from LIghtboost.
The Asus VG278Q and Dell U2713HM do not use PWM and are truly flicker free.
In a 24", my suggestion instead would be the Dell U2414H.
120 Hz and 144 Hz monitors are designed for gaming, aimed at people hoping it will give them some minute advantage in multiplayer FPS games. To achieve this they sacrifice image quality. Don't expect them to be easy on sensitive eyes. The Asus ROG PG278Q is the first monitor to try and bridge this gap, which is why it is so expensive.
Whatever monitor you consider, search for a review at tftcentral. They do real reviews and are a great source of information.
They also maintain a list of flicker free monitors:

I have already made my mind about going into 144Hz 1ms. That's what I am going to do.
Regarding flicker free monitors:
Both: BenQ XL2720Z and its 24" counterpart: BenQ XL2420Z - Are in fact truly flicker free, according to the chart in the Flicker Free Database link you just sent me (http://www.tftcentral.co.uk/articles/flicker_free_database.htm).
So actually both the BenQ XL2720Z and BenQ XL2420Z might be the best options for me at the moment, as it seems the Asus Asus VG248QE, as good as it is, doesn't qualify for a flicker free monitor.
Also Linus and Tom's Hardware mentioned positively the flicker free new tech behind the BenQ (something with direct current instead of pulse) to work very well. Although the reviews I read were only about the BenQ XL2720Z. I am assuming both are the same exact monitors with a different resolutions.
How bad is the issue of "pixel density" getting reduced when going 27" with a 1080p resolutions, both reviews I have mentioned + other people mentioned it means nothing, and it looks great, unless you really looking at it from point blank. Others says its absurd etc etc...
I honestly think that if pixel density would be such a huge issue, the monitor would not receive such positive rankings.
However, if you think its really that big an issue, I can go with the smaller XL2420Z - if it's indeed the exact same monitor spec/tech wise.
However I rather pay a few extra $ to get the 27"..
Tell me what you think about the BenQ XL2720Z picture quality, speed for gaming and flicker free tech, please.
