Is there really that big of a difference between S-Video and RGB on SNES?

Hate to bump an old thread, but I've been thinking about this recently and I'm trying to figure out why this is. Perhaps the SFC and SNES use composite video for sync instead of a proper sync signal?

I doubt it has anything to do with that, on the model 2 I have my monitor is taking sync off of the composite video line, looks great.

In fact a while back I bypassed the RGB/Video encoder on a model 1 PCB I had laying around, and installed an RGB amplifier, the picture looked a bit better but was still soft. Looks like the PPU is outputting the video that way... didn't look at it with a scope.
