In my humble opinion, '?' is to be preferred, leaving as it does a sense of the mystery, of searching out the unknown, of the pursuit of further knowledge. By contrast '.' is almost an obscenity, declaring as it does that there is no more to be said, a prejudicial epithet to the yearning of the human psyche to discover, to explore.

While '.' carries the ultimate simplicity of a full-stop, the elegance of a single point in space, it is nevertheless the cold finality of the finishing of a thought expressed, allowing no extension and brooking no opposition. '?' leaves open the possibility of a '.' to be had in the future, perhaps at the end of all things, but to assert '.' from our limited perspective at present is mere presumption.
