Some objections to Condorcet could be: 1. It is not expressive enough (compared to ratings)Truly less expressive in some ways than ratings. This is balanced by not demanding ratings details. And more expressive by measuring differences between each pair of candidates.
"Demanding" is an odd word to use for "allowing." "Condorcet" doesn't really refer to ballot form, though it is often assumed to use a full-ranking ballot. In any case, a ballot that allows full ranking, if it allows equal ranking and this causes an empty space to open up for each equal ranking, is a ratings ballot, in fact. It's Borda count converted to Range by having fixed ranks that assume equal preference strength. Then the voter assigns the candidates to the ranks. It is simply set-wise ranking, but the voter may simply rank any way the voter pleases, and full ranking is a reasonable option, just as is bullet voting or intermediate options, as fits the opinion of the voter.
