I have never regarded the direction of airflow between sides as all that significant. There are larger influences from variations in the tapered parts, so that probably explains why I find Alex 103's a little smoother than Paxman 20's with valve changes, even though theory would suggest that the Paxman valve system should result in smoother changes! Geyer vs. Kruspe wraps is a pretty pointless discussion really, as good examples of both will be found.
