There's definite differences between the three usually, but since I have gotten my Pioneer Elite widescreen, the differences are definitely less significant, due in large part to the what the Pioneer set itself can do, since it has built-in P-scan enhancers and such.

Using only the direct inputs to the set, I've found that there is a very slight difference from VHS composite to VHS S-video, almost nothing is noticable on well-recorded, newer factory tapes. There is actually a better image on Laserdisc composite than S-video, which has more to do with the system of recording on LD and the use of a better comb-filter by the set than the LD player and this is not an unusual finding. Surprisingly, with DVDs, the differences between the three compared side-by-side on the Pioneer set with the same image is negligible. I would think that the differences on lesser quality sets would be more significant.

Since I put all the devices through a DVDO enhancer, all of them are converted into P-scan component output with any necessary scaling done by the DVDO, and that's the absolute best image of all.
