Madoka became a concept of the Universe, basically becoming omnipresent. She was in every space and time and became a God-like figure.
Sailor Moon has some FTL feats like flying to the center of a galaxy. Again they have been inconsistent with other showings. But she is capable of a number of things at her max like reviving her friends from the dead and resetting the earth. She did show the ability to strip aliens of their power in the second arc and cleanse evil, not that the latter applies to Superman.
