Kent uni or Sussex uni?

I will be studying anthropology and have trying to decide between the two for about 4 months. Lots of people tell me it's a no-brainer as I have an unconditional from Sussex but not Kent. Falmer is beautiful, Brighton is amazing and the course is nice, too.And the unconditional- I suffer with anxiety and so this is ideal as much of my anxiety is based around stress which is more prevalent in exam time.
However something is holding me back from firming Sussex and frankly I don't know what it is. Kent was originally my favourite uni until Sussex offered me an unconditional, and then I began to consider them more seriously. I prefer some aspects of the anthro course at Kent (the flexibility and the fact that I know other courses they do if I wanted to change) except according to stats, Sussex seems further ahead. I love the student support at Kent however I am not aware of what it is like in Sussex. I love the idea of vibrant Brighton but also I love the charm of Canterbury. My boyfriend is also going to Kent and whilst this is not a determining factor, I am being holistic, however I am not sure if it would be better to go to a different uni or the same one.
Has anyone got any info on either of this unis that may persuade/ dissuade me on one of them, or any opinions on what I should do? Any help would be much appreciated now as I am entirely stuck, thank you.
