CompSci or NatSci

I'll try to make it short:

Got 3 A*s (maths, phys, chem) last year but applied for low-tier Unis so decided to hold out and apply for Oxbridge. I've also picked up Further Maths too to give me a helping hand.

Always had my sights set on CompSci at Oxford, as I found the CSAT crazy hard. But now I'm starting to think that even the MAT for Oxford is pretty hard so I'm kind of stuck. I know that you can specialise a NatSci Cambridge degree and any degree from Oxbridge is quite highly valued in terms of Job Prospects; so now I'm wondering if it would be easier for me to get into NatSci at Cambridge instead.

I'm not sure if I'm just overthinking but any help would be brilliant.

Apply for the course you most want to spend 3 or 4 years studying, not because it's easier to get into (it isn't...)

Honestly they're both brilliant, CompSci seems to go deeper into one topic whereas NatSci seems to be more general - both of which are pretty appealing.
