No University is going to suit everyone who goes there. This is why it is so important that you go to Open Days etc and think about the reality of spending three years in that place, and not making this decision for superficial reasons.
Overwhelmingly those who do go to Sussex love it - both the University and the town. And employers arent that picky, despite what school leavers love to believe - my degree from Sussex has never, ever, been sneered at. If anything, Sussex grads have a reputation for independent thought, concern for social justice issues and dont obsess about 'salary', more often simply being content to contribute something to the world, to 'make a difference' to the lives of others, without feeling the need to strut about the world stage showing off - the world has been made a better place by many, many of then.
