Which should you learn first?

Study time will not decide this one, because the two ask for about the same. If you want to reach a particular place, a person or a job, start with the one you will actually use: steady motivation counts for more than the difference in hours. Because they share so much, you do not need to pick one forever. Learning one first makes the other noticeably quicker, and the main risk is mixing the two up, so give the first a solid base before starting the second.
