This is a very abstract question. Most would answer the marshal, but the fact that the opponent has a spy in a way equalizes the marshal s and the general s value. But if you are up a marshal, for instance, and the opponent still has his spy, then you should try to capture his general and lose your marshal, cause then you would be up a general and your general would be able to attack any moved piece without the fear of being captured by the spy. So, in this case, the general would be the most valuable piece. Another example: if you hare left with a miner and the opponent is left with a higher piece, your miner is possibly more important than the opponent s piece (if somehow you manage to force him to allow you to get to his flag using the 2-square rule or the rule that the other player cannot threaten your miner forever).
Winning isn't everything, but wanting to win is.
