Good job with the specifications to both machines. But I think the Helepolis will win because it's so damn larger than the tank. It's usage in combat, however, was in one word: never. After it's construction by the Antigonid Demetrius Poliorcetes to take the island-city Rhodes, he realized that the Rhodians were watching his construction the entire time and would probably be assessing it's strengths and weaknesses already, so he just had his Helepolis destroyed.
