You choose the size not by the advantages but what you are going to do with the folder.
If you are going to use the bike in multimode commuting using the bus, then the 16' inch folder is the best way to go. If you have an airplane or small boat, the 16' inch folder is the best way to go. Otherwise, you would be better off with a 20' inch folder.
