Favorite is Assos Creme which is expensive but feels so good (it's metholly so if you don't like that this is not for you). I usually (if it is needed) apply it to the chamois and girly parts. But I also like that Chamois Butter makes small, individual application sizes you can carry on the bike. If doing a week long ride, I start with the Assos but carry the Chamois Butter mini's just in case.
