Use discretion with regard to published projector specs. They are rarely truthful. What you really need to compare is specifications with fully calibrated displays. Calibrated to the same standard, like D65 / rec 709. JVC tends to have the most realistic specs.
The JVC, even though the specs indicate otherwise, will have a higher contrast as it is a native contrast that does not use a dynamic iris to pinch in on the light path to give the impression of increased c/r.
LED based DLP machines do not create a rainbow effect, but unfortunately, I know of only one on the market right now and it runs about 10K.
Both LCD and LCOS/DILA (LCOS and DILA are LCD based machines) exhibit more motion blur than DLP, which I am sensitive to.
I guess what I am trying to say, is that there are pro's / con's to each and one has to figure out what they can and can not live with and live without. If you are into accurate "film like" displays, go with JVC. If you like crispness and "pop", go with DLP. But if you get headaches from DLP induced rainbows, you will have to live with motion blur.
If you are not in a hurry, I think there will be some significant improvements within the next six to twelve months as LED becomes more mainstream. And if you are really patient, wait 24 months for laser based projectors.
Or, just buy whatever you can afford for now and be done with it, and don't read forums.
