Thats a simple question with a rather complicated answer. It really depends what values you hold highest.
Pros: very good black levels, great contrast (they are typically very bright) and the color reproduction is good to excellent. No chance of burn-in.
Cons: In my experience, they tend to highlight noise in the picture, they can tend to obscure shadow detail and can have other picture irregularities like banding between color transitions. Vertical viewing axis is somewhat limited. Not a flat panel technology.
Pros: Bright, punchy color (though not always technically accurate), flat, no chance of burn-in.
Cons: Black levels are still the worst in all of the technologies (they will tend to look dark gray rather than true black, and when you sit off angle, you'll see a shift in black level (it will get lighter), color reproduction isn't quite as accurate as plasma. More expensive than DLP.
Pros: Very good black levels, accurate color reproduction, flat, perfect off-axis viewing angles.
Cons: Not as bright as DLP or LCD (not as good for bright rooms or daytime viewing), can have a noisy looking picture (in the cheaper models), glass screen produces more glare / reflection. More expensive than DLP.
Sony SXRD Rear projection -
Pro's: Very good black levels, accurate color reproduction, smooth film-like image, good shadow detail.
Cons: Because it is a rear projection tech, the Vertical off-axis viewing is somewhat limited (similar to DLP), not a flat TV
In my opinion, if you are looking for a less expensive alternative to plasma and LCD, and you don't care if your TV is flat, I recommend the SXRD over the DLP.
Please understand that my generalizations about each technology are just that, generalizations. Not all of the described qualities will be present in every TV of the same tech type. In the end you really just need to go to a local retailer like Best Buy and stare at the different models in your price range for a while. Use my descriptions only as a starting point.
