Sperm Whale vs Orca
Quick answer
In a hypothetical one-on-one, the Orca would most likely come out on top in most encounters, thanks to its more dangerous natural weapons and superior speed. In reality, animals like these rarely meet, and both would usually avoid a fight.
This is a hypothetical, educational comparison based on typical size, strength, and natural weaponry. In the wild these animals rarely meet, and most encounters end without a fight.
