All I can say is apparently Danzo ages better than Hiruzen, because Hiruzen was stated to be stronger than Danzo when they were younger.

Thing is though, do we know for sure that Danzo had the Sharingan implants in Part 1? I don't remember if it was confirmed or not. Also, maybe his abilities were enhanced later, and maybe that's why in Part 2 he would seem much more powerful than Hiruzen.

Or maybe he just aged way better and this fight is all his. Who knows.
