I agree that the greatest factor is in the caster rather than the rod. However, I think that some rods are inherently more accurate than others.

If you have ever built a rod and found the "spine" of the rod, you can understand that the bending characteristics of rod blanks vary. Some blanks have a more pronounced spine, or preferential bending direction. Some blanks even have a different spine direction depending on how deeply the rod is bent. If the blank is bent just slightly, the preferred direction may be off by as much as 20 or 30 degrees from the spine direction when it is strongly bent. This means that the tip of the rod will track differently when the rod is lightly loaded to when it is heavily loaded. If the rod tip does not track the same at light loads (short distance) from how it tracks at high loads (long distance) the rod will not feel as accurate.

The manufacturers of rod blanks have gotten much better at making the blanks with less pronounced spine and more consistent spine in the last couple of decades. I think this has had a big effect on newer rods being more accurate.
