To be honest, it depends on your students' age levels and experience using technology.
If you present a student a screen with two submit options (one that says Submit a new attempt, and the other that says Submit based on a previous attempt) you're going to have kids who have no idea what the are expected to do. For this reason, I don't use the submit button (they forget to click it always all the time and I end up with draft submission that never get submitted). But, this does mean they always have access to that submission. There are times kids revise their submission two or three times before the teacher even gets around to grading, but I guess that's okay right? In that case, the teacher is grading the latest version of the assignment anyways. but if that's not ok for your school setting than the submit button option still doesnt stop kids from submitting a new attempt.
Quiz Module clearly limits how many times a student can submit the quiz... you can set "1"
Assignment Molde not so clear. You may only want a kid to submit 1 time, but the settings don't quite seem to allow that unless I'm way off the mark. There are so many combinations of options.
