The basic concept behind both extensions is the same. Someone from the community who has used both would be able to better offer opinions on the techniques used.
As a former member of Team InterAKT and ADDT even I have to admit the WebAssist Includes is better than the ADDT Includes. And the ADDT Includes were awesome.
If Includes is your thing, as it is for me, you will not be disappointed with Framwework.
