--- Comment #6 from James Cloos <cloos at jhcloos.com> ---
I only took a quick look.

pdf1 uses tranparency.

pdftocairo uses deflate to compress the images; pdftops uses rle.

pdftops rasterizes the whole page; pdftocairo tries to avoid rasterizing
areas which would look the same were transparency not involved.

Whole page vs just the image is the big difference.
