Personally I find LCOS to be a superior technology to DLP at this time.

Reason beings -
* Most DLP sets are still "wobulated", not true 1920x1080 resolution being displayed at once. It is perceptually full 1080p, but 1:1 pixel mapping is not truly possible as a result.
* While LED DLP sets have improved or removed "Rainbow effect" for some, the first model year of LED DLP suffered from poor contrast ratio and now the second model year which looks better suffers from a new "Prism effect" artifact.
* DLP seems to be less reliable than LCOS. Looking at various forums it appears not uncommon for something to go wrong with the $1000 light engine within 2 yrs of purchase. They have not seemed to have gotten the process down yet. Some even have to replace the light engine out of the box.

With that being said, TI now has out a full resolution unwobulated chip that does 1920x1080 resolution - however none of the current sets use it.

Also, looking at some of the new 3D technologies and how they are projected, its possible DLP may have a leg up on LCOS/LCD in this area looking far ahead in the future - although a simple stereoscopic 3D effect would most likely be possible on LCOS as well so long as the set is 120hz.

However with the negatives in mind, it is hard to generate a good list of "PROs" that overcome LCOS lack of weaknesses with the latest sets. Perfect convergeance might be one, though LCOS is pretty damn good out of the factory in most cases. Response time no longer seems to be an issue with LCOS.
