It's not equivalent.  \partcombine is most useful for piano extracts: it
will combine notes of same length into chords and keep notes of
different length separated.

will keep even notes of the same length in different voices (and
consequently with different stems).  Which is often what you want in
partiture in order to be able to tell different voices apart.
