i would just say, and i iknow youll hear this a lot, but you should do whatever you prefer, regardless about your later plans. after a normal degree as opposed to a LLB you only need to do a one year conversion anyway.
its nice saying you do law at uni for the prestige but that wont help you when youre revising during your exams and doing all nighters! really dont let it affect your decision
do what you prefer and youll be equally fine, its a long video but a justice of the supreme court, lord sumption debated this at the cambridge student union (he was a historian academic before he became a barrister, then supreme court justice) and its well worth a watch,
good luck
