I am afraid you must be a little more specific about what you mean by «killer sharks».
To the best of my knowledge, there is no shark commonly know by the name of «killer shark».
A great white is a killer shark, as well as tiger sharks, bull sharks, and so on.
Yes, killer whales are very strong. stronger than a white shark or other bigger sea animals
A killer whale is stronger than a crocodile and a shark combined.
An adult Orca (Killer Whales) will generally always beat an adult Great White Shark. Orca are smarter and rely on sonar. Orca also travel in pods and Great White Sharks do not, so in reality, Orca would always be able to kill a Great White Shark.
