I don't know much about law, but my sister was in a similar situation to you last year - deciding whether to firm Nottingham or Bristol.
I can't say much about which is 'better,' but my sister ended up picking Nottingham and is loving it so far. The campus is beautiful & the teaching, though online, has been great. I'm not sure if Bristol offers something similar (though I'm sure a quick Google search would do), but Nottingham's Law LLB has the option of applying to a 'year abroad,' given you're doing well & have the grades. It's quite competitive to apply for, but definitely worth it as my sister is an international student as well, so the fact that the university connects you with other prestigious universities (closer to home for us) including Singapore's National University & a handful of universities in Australia is great, as it helps if you want to work there. Also, where I'm from, Nottingham is more 'known' than Bristol as they have campuses in Malaysia and China as well. Just something to keep in mind if you're hoping to work abroad.
