Just a mnemonic to remember port and starboard. Port and left both have four letters. Also, port is a shorter word that starboard; left is a shorter word than right. With respect to the running lights on ships and aircraft, port is red wine so the red lights are on the port or left side and the green lights are on the right or starboard side.

As for the original question, I have no preference. If something is that spectacular to see (e.g., leaving Venice, Stromboli, Panama Canal), you are going topside anyway.
