An island is a different animal from any inline booth. There is no back wall, which means there is nowhere to put a big graphic and nowhere to quietly store the things a booth needs. Every side faces an aisle, every side faces a different crowd, and the design has to resolve all four at once. That is why a 20x20 is where exhibitors usually bring in a real exhibit partner rather than ordering from a catalog.
The upside is presence. A 20x20 at the Tampa Convention Center sits in the open floor, often near the larger anchor exhibitors, and a clean overhead structure or hanging sign can be seen from across the hall. Used well, the four-sided exposure does marketing work that no inline footprint can match.
