I have always had a soft spot for Geography, perhaps because I failed my 2nd year History exam back in the 70s and have never quite gotten over it.
I feel that history is more high-brow - it suits the artsy/English Lit people more. Geography is a little bit more leaning towards science. History probably has slight better field trips than Geography - more comfortable, physically.
A-level Geography is apparently the easiest traditional academic subject to get an A in.
My eldest kids have done both for GCSE.
