Are there no Buddhas from other universes that are equal to our Buddha?

Buddha said "nowhere between the lowest of hells below and the highest heaven above, nowhere in all the ***infinite worlds*** that stretch right and left, is there the equal, much less the superior, of a Buddha. Incalculable is the excellence which springs from obeying the Precepts and from other virtuous conduct." - **Apannaka Jataka**
