"Less contact with the road" does not equal "less friction", which in my humble opinion leads to a lot of the confusion surrounding the subject. The shape of the contact patch does alter the rolling resistance, to some degree.

As for the question itself, I personally prefer 25's to 23's but if you pinned me down about "more speed" I'd have to admit that I don't see any difference at all in practice.
