Not really relevant in this context.
What are your current study subjects?
What are your interests?
What do you think of the course structures and modules?
Have you looked at what Oxford has online on these courses?
Have you looked at YouTube for the Oxford uni for perhaps demo lectures and so on?
Follow your interest at this stage perhaps. Both will have superb career prospects and I doubt either course would limit you to future work over the other.
I think this is one where you’ll have to dig into Oxford’s own online info including YouTube to build your own picture.
