Ok i lied, last post lol.
I did an incredible amount of research before i bought my s2417dg, it easily has the least amount of panel uniformity issues/backlight bleed than monitors costing 2x as much. Feel free to browse this thread: (generally considered one of the best monitors out there, 144hz, gsync, 1440p, IPS)

The thread is filled with reports of backlight bleed/panel uniformity issues. To the point people have referred to this as taking the "XB271 panel lottery" trip.
Now browse this thread:

The worst complaint about this monitor is its calibration for gamma out of the factory isnt as good as many VA panels. This can be fixed in nvidia software but whats funny also is many of the complaints about gamma in this thread is people confusing low bitrate video or images for poor gamma.
All said and done the dell gsync monitors is really the best you can get currently for a gaming monitor. On top of that it is one of the cheapest gsync monitors currently available on the market, with the best warranty (dell will SEND you a monitor before you send yours back if you did not like the one you received) and the best quality control in the business, dell has done this longer than any of them.
Again if you are the sort of person who does both watch movies and game on a monitor a VA is a solid compromise. If you game on your monitor and have a proper TV for your movies then the dell is currently the best choice as a gaming only solution.

Some people do put vibrancy over contrast/uniformity for a TV set (this is where samsung shines, their quantum dots), but most will prefer and OLED in a blind side by side test. Samsung currently does not dabble in OLED but i will bet any amount of money they will have to soon, or risk losing out to LG and Sony's superior OLED sets.
