With composite, luminance and chroma are all combined into one signal. S-Video improves things a bit by separating luminance and chroma into two separate signals. Component separates chroma into two signals, making it the most accurate of the three for colors (plus it's the only one of the three capable of producing pictures with more than 480 interlaced lines on NTSC or 576 interlaced lines on PAL, not that it matters on a regular TV). I would venture a guess that the difference from S-Video to component would be negligible, unless your TV has progressive scan, in which case component is the clear winner since it's the only one capable of producing progressive frames. The best way to find out is to try it out though, since picture quality varies from set-to-set.
