Imo HAs by default are better than axepult. Agg nudges axepult back on top. Seville being attackable on turn one pushes HAs back on top. But Agg-AI + cultured hill city makes me favor construction in the end. HAs just too dependent on what that initial defense is and the first few dice rolls, while catapults mitigate that with guaranteed collateral. One final consideration is I might lean back to HAs for the saves with only 3 cities. I expect the strongest T110 save will be from an HA rush that catches Izzy at war with Cathy, but I think a construction rush is a more consistent path to victory.
