Personally, English Literature is regarded more as ‘academic’ by russell group unis. Similarly, to study law english would be a better option to pick. But ultimately go for whichever subject you enjoy more! I studied both english and sociology at a-levels and I really enjoyed both of them (english is slightly harder due to the amount of coursework and writing in exams). Sociology has slight links to law as you look at topics regarding crime, but personally english would look a lot better on your ucas. Hope whatever you choose works for you!
