This really depends on how thick or thin the data are.

If any given option only gets a small handful of votes, then you might see a strong bias (favourable or otherwise) where neutral would be appropriate.

In Likert scale design (where favourability options >2), there's a strong debate over even or odd choices -- should someone be able to give a "meh" rating, or do you want to force a positive or negative, if even slight.

Hence, 3, 4, 5, 6, and 7 point (typically) scales.
