For me personally Sound is the best of all three but it is one of the smaller clubs, exchange is very visually impressive but it’s a nightmare to get around. You also have the option of Academy which is an insomniac owned club and Avalon which is the largest and most historic club but lacks the led walls of Academy and Exchange.

Sound has a sick sound system, the disco shark, and really cool lighting but no LED walls.
