Just because you're renowned for something doesn't mean you're the best at it.

Kakashi of the Sharingan was not better than Itachi with the Sharingan, but still carried the title.

Shikamaru was known for how intelligent he was, yet Kakashi was stated to match him in intelligence.

Minato is leagues above other Kage in speed. Shisui may be known for his Shunshin, but that doesn't mean Minato doesn't at the very least match him. If his Shunshin was mistaken for FTG at some points, then you know it's insanely fast. So Shisui really hasn't shown anything impressive enough to surpass just Minato's Shunshin, much less his FTG.
