The 'Manzano' have thin skin and more rounded fruits, whereas the 'Brazilian' has thicker skin and rather more angular fruit. But that doesn't really mean that what you had was either necessarily. The photo you show from Jon's site is 'Mazano'. It's really hard to say what variety you ate unless you could show us a photo of the actual fruit you ate, preferably on the plant. The fruit bunches look very different, here are some photos.
Manzano type, 'Ungoye Sweet'
'Santa Catarina Prata'/'Dwarf Brazilian' ("Hawaiian Apple"), one of the most common varieties in Hawaii.
