History and Politics advice?

I've applied to Warwick, Bristol, Southampton, Sussex, and Queen Mary's, and have had offers from all of them for History and Politics,

Warwick - AAA

Bristol- ABB (A in History)

Southampton - AAB

Sussex - AAB/ABB

Queen Mary's - ABB (interview for unconditional coming up)

Does anyone have any advice, or any unis they would recommend going to/avoiding. I've heard really mixed things about Bristol and Warwick, with some people who I know having been slightly disappointed with the support and teaching - albeit for different subjects.

I'm ridiculously indecisive and keep switching where I want to go.

Any advice would be welcome.

Have you been to open days for any of them? Have you made a pros and cons list for each university?
