Are female dogs (of any breed) easier to train than males?

Lets say someone gets a dog that requires more socialization and training than your typical Collie or Golden Retriever. They are bull mastiffs, GSDs, APBTs, Cane Corsos, Rotts, etc.

I'm guessing just like differences in genders with humans, there must probably be difference between female and male dogs. Do you think a female dog (of any breed) easier to train than males?
