Overall many people would have to agree Michael Phelps (USA) is definitely the fastest swimmer in the world but their are others like Brenton Rickard (AUS) in breaststroke and the Brazilian swimmer Cesar Cielo who is definitely along side him in the Butterfly 50m.

Asking "who is the best" for anything will get you no answers because nobody knows every single person in the world, therefore there can be no answer.

We all have our opinions of who is the best swimmer. My opinion is/was Michael Phelps because he won 9 gold metals in 1 Olympics (Beijing Olympics in 2008, summer). So he must be pretty good.
