All NTSC letterbox (non anamorphic) suffers a little from jaggies on lines that are just off the horizontal - it is purely a function of the reduced resolution available, however they are nowhere near as bad as the pictures posted here.
There is little difference between the faces and definitives in this regard, though the faces are *slightly* better.
The pics that were posted here of Leia in the war room had excessive sharpening, and a low dynamic range which made the problem look much worse than it actually is.
On the PAL set you get less jaggies in general because of the extra resolution, and the tighter framing i.e. it is 'zoomed in' more, so you lose some picture, (pan and scan 'lite') but what is on screen is bigger, so more scanlines to go around.
Short answer - they look good on our transfer - I'll do some pics over the weekend to show what I mean.
