This page provides additional information about Kali packages which are not in Debian: https://pkg.kali.org/derivative/kali-dev/#new_pkg
It used to contain a table with info from all the packages, but the wiki doesn't work well with that (the rows were too wide and wiki were having problems formatting them), so at least for now there's gonna be a .ods available at a given link below, and also a gdocs spreadsheet. Both with the same content.
The info was generated using the following script: https://salsa.debian.org/samueloph/gsoc-kali/blob/master/kali-packages-checker
The google docs online spreadsheet is at (gdocs is non-free): https://docs.google.com/spreadsheets/d/1muSrob3G1c7ZwHlxfDAho4qtdJ9pZNycCKT9kWyIJkw
For a view of the spreadsheet hiding the packages that are already on debian, look for: Data -> Filter views -> not-on-debian
There's also a .ods formatted spreadsheet available for download at https://salsa.debian.org/samueloph/pkg-security-team-kali-spreadsheet/tree/master
