MUCH smaller file sizes courtesy of JBIG2! And the possibility of JPEG2000 for color images. PLUS, the ability to do "image segmentation"

JBIG2 and JPEG2000 use patented algorithms so they are not as useful as they should be. TIFF can easily be extended to support these compression schemes. Of course TIFF is still limited to being a simple raster format while PDF is free to support boundless complexity.

Don't get me wrong - TIFF serves a variety of purposes, but long time archival storage is NOT one of them.

TIFF bits are no more susceptible to 'rot' than PDF bits. They are still just on or off like any other form of bit.

I think that the usefulness of TIFF or PDF depends on what you need to accomplish.
