Because Saturn literally needed to completely transform, then attack Sanji and then stop him moving, while with Sabo they didn't even completely transformed, but 1 attack was already enough to put Sabo in bandages for several arcs post-Mariejoa incident?

Congratulations, a worse feat than base Sanji against a serious and completely transformed Gorosei.
PS: Sanji didn't try running away for his life

Sabo was also not downed by the Gorosei but by Imu.
There are so many ways to debunk this thread and you went full headcanon on it.
