Pound for Pound, who takes it? Kessler is smooth, has steele skills, thick defense and is ice cool. as is winky and calderon, but all have different variations of the same style.
I wouldn't really put Calderon in the same bracket. Some loose comparisons could be made between Wright and Kessler, stance aside. Good jabs and straight right/left, high guards, not a huge amount of movement.
