Which characters seem most real? Which is the most interesting? (In Treasure Island)

I like the spirit of adventure and of course the pirates. Long John Silver is my favourite character. Long John Silver is an old sailor cook, the leader of the pirates, and one of Jim's friends. This dynamic character has only one leg, and is usually accompanied by his parrot, Captain Flint, who hollers "Pieces of Eight, Pieces of Eight." Many critics claims that Long John Silver is the novel's real hero, and not Jim Hawkins or Flint's treasure.
