Generally component will give you a better picture, but a lot depends on 
what you are watching it on. NTSC encoders and decoders cause 
degradation, but as in all things there are better and worse encoders and 
decoders, as well as differing tolerances on the part of viewers.

Assuming nothing else is the "weak link" in your system, I'd go with 
component, unless the reliability increases enough with something else to 
make it worth putting up with an inferior picture.

In order of quality:


HDMI would be #1 or #2, depending on several factors.
