Exeter or Leicester Uni?

I'm studying Biological Sciences at Uni next year but can't decide which of these to firm and which to put as my insurance. There are so many factors to consider!

As a whole, I think I prefer Exeter, however the stereotype of the students there does freak me out a bit, as well as the cost of living and the fact that my best friend has also firmed going there.

I did really like how integrated leicester campus was into the city, but the Exeter campus is sooooo nice!

The main thing that's getting to me is that I preferred the optional modules in years 2 and 3 at leicester than at exeter, which feel like an important factor.

The labs at exeter are also massive, with space for around 200 students in there or something crazy, whereas at Leicester it is much more intimate in the sense.

Leicester is BBB and Exeter is ABB, however if I firm Exeter it will get lowered to BBB.

And these aren't the only things I need to consider!

I'm so so torn and would appreciate any opinions or any advice on how to decide.
