Some decisions, such as whether to drink white or red with a meal, are easy. Others are less so, for example, which broker to go with when buying or selling a Hamptons home. Of course, personality matters, but because this is the East End—where the largest, trendiest, or priciest of anything is often considered the best—who handles the biggest deals is often a deciding factor. Success breeds success here, as anywhere else. And if brokers are what they list, then those with homes in the rarefied air of the super luxury market—houses priced for $20 million and up—enjoy celebrity status.

Land sales weren’t included; neither were open listings, although shared listings were taken into account. And sometimes, one colossal listing was all it took.
