Nice pick!
But there's always a clear winner regardless of the subject. For instance, the greatest rock song of all time is "Stairway To Heaven". As much as I love "Freebird" and "Smoke On The Water", nothing holds a candle to "Stairway".
Another example, the best breakfast cereal is clearly Lucky Charms. The competition is really for what's second best. Whether it be Frosted Flakes or Cap'n Crunchberries or Sugar Smacks.
Nobody can argue against Snickers being the best candy bar. The real argument over what is second best. Heath or 100 Grand or Almond Joy.
The best movie of all time is unquestionably "Casablanca". Too many other movies to list that might be second best.
But these are always fun to participate in.
