I think that the best way of choosing the best suitor is to take first one that impressed the most. In this way you choose the best one for you. You don't have to take chances. It's like in life. You meet a girl (or a boy) and you like her, then you get married. You don't know if she is the best one you can get. But it doesn't matter, the most important is that YOU think she's (or he's) best for you. Maybe my thinking is not strictly mathematical but that's first what came into my mind.
