Component Video versus S-Video

How important is it to look for component video inputs in a new processor versus using high-quality S-video? Is there really a huge difference?

Some processors only have composite and S-video inputs, but everything else I need is there. Most processors I've seen that have all the inputs I'm looking for plus component video inputs are much more expensive. Is it worth the cost difference?
I wouldn't worry about the sub crossover at 100 hz. You probably want some significant overlap, so unless your mains and center go REALLY low, 100 hz is probably OK, IMO.

Based on distortion and frequency response specs 100hz crossover in often ideal.
