Danzo is nowhere weak though and it's not like we actually know how it happened in the actual canon. Danzo could of used various methods to acquire his eye. Poison is a good example. Even just catching him off guard. Utilizing numbers.

Not to mention he was Kage caliber.

So a few reasons why Sasuke did what Shisui could not.

1) If you go by what the wiki says, Shisui practically one shot Danzo with Genjutsu to the point that he needed to use Izanagi. Of course, this caught Shisui off guard and unlike Sasuke, he didn't have a Susanoo around him keeping him safe already. So his eye was stolen. It was the surprise of that, that got him, and it would of got Sasuke too if he didn't summon his Susanoo from the gecko.

2) Once Shisui lost his eye, he knew what Danzo was after. Rather than fight and risk losing his other eye, his only method at that point was to retreat.

3) It was still stated he was a better Genjutsu user. Danzo getting his eye, doesn't denounce that.
