CoB is one of my favorite games. It's also been a huge hit with my gaming group, and I will say that it helps a lot to have all players in the game be experienced players.Therefore, my suggestion would be to teach people the game with either 2 or 3 players, and then try a 4 player with all people that know the game. All of us know the game well at this point, so we really can set it up and get going quickly.
The game really moves at a good pace with experienced players, and the 4 player board really offers you the most dynamic choices. It's actually my preferred player count, but you do need all players who know the game.
