On Maimonides tomb is written the epitaph: “From Moshe to Moshe, none arose like Moshe!”
We can read in many sources (e.g. http://asknoah.org/essay/rambam) that this implies Rambam was the greatest of all rabbis since Moshe.
But what about someone like Rabbi Akiva? Wasn't he just as great or greater? According to the Talmud, Moshe Rabbeinu did not understand Rabbi Akiva's lectures.
How seriously are we supposed to take the "From Moshe to Moshe" epitaph, and what does it mean halachically?
This latter question is relevant because of Deuteronomy 18:15-19 (https://www.biblegateway.com/passage/?search=Deuteronomy+18%3A15-19&version=ESV)Deuteronomy 18:15-19.
