I can tell you that article is silly. It depends on what type of content you are watching and how close you sit and how perfectly converged the LCD is vs. what DLP we are talking about. To sum this up, if you are talking about home theater LCD projectors, there is really only ONE LCD projector I know of that is even really competitive in image quality, and that is the Epson 5010/5020/5030. The only attribute that this particular LCD projector really beats single-chip DLP's is black levels, and even then it's certainly not a large lead over a projector like a Runco LS-3/PD8130 or Runco LS-5/PD8150 (though the Runco's new are more expensive). BUT IMO, since the Runco has a far superior IRIS to the Epson 5010/5020/5030, the lead the Epson has in black levels is partly diminished. The Runco has a tighter pixel fill and produces a more consistent image, so overall I'd prefer the Runco unless you need a light-cannon mode which the runco does not have.
If we are comparing other DLP's, like the Benq w7000 or w1070 to the Epson, well the Benq produces a sharper cleaner image, but the black levels are easily beaten by the Epson. The Epson also has much better contrast in 3D, but for 3D gaming LCD is unuseable IMO due to ghosting / cross-talk (I don't know how people even use LCD's in 3D games, seems insane). For 3D movies, the Epson has much higher contrast until you get into a DLP like the Sharp xvz-30000 which isn't as good as the Epson but gets close enough to please most. As the lamps age on an LCOS or LCD projector, the 3D ghosting increases over time and eventually even 3D movies start showing considerable ghosting in 3D, a problem DLP does not have. Of course the Runco LS-3 and LS-5 do not have 3D capability, so that is one issue there if you are into 3D.
For 2D, IMO, DLP wins in most content if you have at least the black levels of something like an Optoma hd8200/hd8300 or Sharp xvz-3000. For really dark movies, the Epsons still easily beat the Benq's though.
A low-cost DLP can still beat an Epson for general TV watching (Discovery, News, some movies) and DLP looks cleaner than LCOS and LCD (noise is less highlighted). Now adding LCOS into this comparison, well LCOS is at its best when something was shot on reference NON-DIGITAL material (35mm,60mm, 70mm, whatever), whereas in this last case I think LCOS can beat DLP overall as the slightly "dirtier" look of LCOS also seems to accentuate the more film-like look of certain movies turning what is sometimes a disadvantage into an advantage.
If a DLP could match the black levels of a JVC Lcos projector, I'd probably prefer DLP in 95% of content, but so far that doesn't exist anywhere near the price range of our sub-$5000 LCOS projectors. So for blacks and dark movies LCOS > LCD > DLP, and for general TV watching DLP > LCOS >= LCD (depends). It depends on the specific movie though, sometimes I think DLP > LCOS and sometimes I find the reverse even when a movie isn't full of dark scenes (Tree of life - crap movie - but good reference content, for instance I prefer this on an LCOS even in the bright scenes).
Hope that helps...
