Are both of those based on the standard oblivion world is there new world content beyond charcters and such?(new dungeons, new towns, etc.)
Integration adds a town towards the end, and a number of new locations in Cyrodiil and the Shivering Isles. At the start there's only a few though, you have to nurture some rising organizations so that they can slowly expand into larger outposts and such.
Kragenir's.... I never really got very far into it. I know it adds some like little altars and cabins and such as quest locations, but I'm not sure if it ever added any big locations. As I recall there was mention of a "Clutter Guild"
If you want some major location expansions there's also stuff like:
Unique Landscapes( makes the vanilla oblivion areas more unique and interesting)

GATES TO AESGAARD (Episode I and II)
All of these either expand on Cyrodiils landscape, or add a new world space you can access.
