What Uni should I pick?

I'm stuck between Uni of Manchester and Bristol. I've applied for economics and received a place in both. I'm not too worried about grade requirements, I care more about the place, the community, accommodation, teaching and opportunities etc. I've gone to manchester once but I didn't get to see the economics department they cancelled their offer holder event. I've never gone to Bristol so I don't really know what to expect. I was wondering if anyone has gone to either of these universities and has any advice on which university to pick. P.S. I applied for economics with study abroad at bristol which I received an offer for. I really want to study abroad and I was wondering if I will be guaranteed a study abroad spot at Bristol as long as I get the grades while in uni. Manchester offers study abroad years but you must apply in 2nd year.
