For serious investors Interactive Brokers is the best. They have the lowest fees, the best execution, the most comprehensive and automatic systems, and the most global reach. However they have struggled a little throughout the financial crisis. They probably fall into the category of "too honest". Most companies succeed in the financial industry by cheating their customers, not by offering them low-priced services.
