BD and SG covered it pretty well. It is just plain easier
to get good results with a (good) 3-chipper than a (good)
one-chipper due to the better tonality and color (and,
often, sharpness and low-light reach). Which is not to say,
as the others pointed out, that you cannot get good results
with one-chippers, or cannot mix one-chippers and 3-chippers
in the same video (I do it often, since I have use for
tiny, unobtrusive cameras close-in...), but it requires some
skill in editing not only to match color balance well
enough, but color saturation, gamma, and sharpness. The
one-chip footage rarely looks as good as the 3-chip footage
even after processing, but it can be made to look similar
enough for a cut-away view without unpleasant surprise...;-)
Also, the best one-chippers, shot in suitable light, can
look good if there is no good 3-chip reference footage
present...;-)
