PDFs can subsume TIFF data and also use the same compression algorithms, so the size issue is likely a wash.
It depends on the software used and the circumstances. For example, I just used a one page text doc as a test. It's grayscale. I saved it as a PDF @ 300ppi JPEG and it comes out 2.1MB. I saved it as a TIFF @ 300ppi and it comes out as 7.6MB. Now take that TIFF and zip it and it's 459KB.
Zip the PDF and it's 1.8MB.
Save the PDF as ZIP and it comes out as 545KB. So there's a 15-20% difference between saving a PDF with zip compression and zipping a TIFF of the same file, res...
With a "15+ pound bag" of paper, 15-20% is not really a wash.
Of course, I'd just run OCR and make it a PDF so it is searchable and copy & past'able.
