After going tenkeyless and compact, I could never game on a full size board again. The ergonomics just isn't there.
IMO backlighting is rarely done well, and usually looks gaudy / tacky. However, I am one to still appreciate a clean, not-too-bright, preferably White backlight, because I often game and type in the dark or low light conditions. So for me its much less of an aesthetics thing, and much more of a usability thing. That is why I like backlit.
I would likely buy something like a Ducky Shining in White if it were tenkeyless. If the RACE keyboard were released in White LED I might consider that, too although there's something a little off-putting about its layout.
Regarding Monoprice, I'm not familiar at all with that company, but the board in that picture is an example of my opinion on back lighting done poorly.
