LCD technology, IMO is superior to DLP. DLP sets can have color artifacts that LCD's dont. DLP uses a 'color wheel' moving real fast to get the colors. To me, that's sort of like the old 'passive matrix' color LCD in early laptops, whereas each pixel had to wait a short time to be lit. Modern laptops (and LCD TV's) use Active Matrix where every pixel is directly controlled.
That's the tech side - from the "eye test" LCD is clearly superior IMO.
