Amerifag here, whats easier, has more jobs, and best opportunity?
You should not pick a major based on any of those three criteria. Just pick whichever you like the most, there's plenty of jobs available for hard + skilled workers in all fields.
That being said, CS has the most jobs and finance is probably the easiest.
