Neither. One format is more convenient for some consumers, the other for
other consumers.

This isn't what upconversion is about. The following would be an
upconversion:

a+b*c  =>  a+(b*c)

because it has replaced external knowledge of the rules governing the
structure (that is, operator precedences) by explicit representation of the
structure.
