I don't have a favorite, just an anecdote. I bought "Lectric Shave" for this purpose, and half-way through my bottle of it I had to stop. Not because it didn't work. It worked great. But the smell was atrocious. I would literally have to step back when I applied it to my beard because it burned my nostrils with the fumes. I think they do make a "sensitive" version (probably for sensitive skin, but hopefully without fragrance too), but I get a good enough shave with my arcitec that I don't worry about it too much.
