The main difference between the two is that in the fully digital kit you get layered PSD templates for the title page, the monthly opener pages and the photo collage pages; in the hybrid kit, you do not. But, you DO get the title page pieces, the monthly titles, and a sketch guide to show how your photo collage pages could go together. There are no measurements included.
Also, in the hybrid kit you get special templates for printing 2.5 x 3.5 photos/journaling cards used to print out manually, and trim, for use in divided page protectors. If you are a digital scrapbooker who wants to use divided page protectors, you will need the hybrid kit for this approach. My goal was to make a kit for digital scrapbookers to fit their needs, as well as those hybrid people (like me.)
I am combining the two kits for use in my album.
