<font color='#8D38C9'>That's a loaded question!
Are you talking about RPTV or FPTV? I can't think of anyone but Samsung making a DLP RPTV but lots of companies make DLP front projectors.
It's pretty tough to really pick a best, partly because it varies depending on what you're looking for. Until very recently I couldn't have taken LCD seriously at all- the space between the pixels was so large that you got a very bad "screen door" effect. Newer panels have alleviated this problem somewhat.
Overall DLP will be brighter with slightly better blacks than LCD. My personal preference is for DLP. But some people are bothered by the dreaded "Rainbow Effect" or "Color Separation Artifacts." DLP (that is to say, one-chip DLP...) uses a spinning color wheel, painting each color sequentially. This means when your eyes are moving you can sometimes see the primary colors. This gives some people headaches. There's really no way to know if you're succeptible to it until you try. For the record, I've lived with a DLP projector for over a year, and I've yet to see this phenomenon while watching a movie.
I love DLP, but my advice is not to buy one til you've had the chance to spend some time watching one.</font>
