Go have a night out in Brighton down Queens/North Street, worst place in the world on a Saturday.
The comment itself blew your whole opinion out of the water, the fact that you cannot even name the roads that you actually mean just compounds the irrelevance of your thoughts. Crawley may feel like some strange Utopia after London if you actually live there, if you are more used to quaint old coastal Sussex then it might feel a little alien by comparison. Either way, one of the two has far higher property prices, make of that what you will.
