I suspect the top selling and favorites here wouldn't overlap very much. There seems to be a strong sense of individualism here. The very nature of DE shaving itself implies a type of contrarianism. This leads many here to avoid, somewhat, scents that many others are also wearing. That said, a well made scent stands on its own, and I don't avoid things because someone else I might run in to could be wearing it.
I'm not sure if I can pick a top five, but I suspect the top two are Cool Water and Acqua di Gio. Of the niche fragrances, Green Irish Tweed seems to get mentioned a lot. I don't know where to place Dior Homme, but it is very popular on fragrance boards. In the end, sample a lot and wear what you enjoy.
