I chose better/better. The tactical AI is still easy, but no longer inept. Other than sitting in front of towers during a siege, it no longer does the moronic blunders that made it easy to kill thousands while losing dozens. When given a large force with cavalry support, the AI even makes use of hit-and-run tactics and army-wide envelopment. Still easy to defeat unless heavily outnumbered, but it requires more careful planning and victories without loss are far harder.

The strategic AI seems to maintain larger armies and lead them with generals more often. It engages in multi-stack attacks more often and seems to obey ceasefires and alliances more readily. Other than with Hordes though it does not attack as aggressively as it should and it again represents more of a lack of incompetence than any actual positive ability.
