Yes. I like the arrange-act-assert ordering of EasyMock and Mockito, but I got used to the JMock ordering fairly soon, so I no longer notice the cognitive load that it places on the programmer. I accept this in exchange for getting the default behavior that I (usually) prefer.
I don't mind having to write in Spock "and nothing else should happen", but before long, I'd want to push that duplication into the background, and the result would look like JMock anyway.
