I personally do not care who wins when one on one. It is easily the Enforcer since the Hammerhead would get eventually tired of going back and forth. Even if the hammerhead would manage to win, it still does not matter. The question is which can survive more than the other in a larger battle. I just can;t imagine the Enforcer being my support since it would not be able to pull back and move behind me to replenish flux, although I can imagine using the enforcer as a shield for sure. Of course depending how one plays, one or the other must be useless. I know that since I love Sunder, I always look for a XIV model. This is why I said it is fine if the hammerhead remains as a crappy craft and then a MKII appears.
