Depends on his composition - archer if mixed, spear if horse, axe if melee.
The point is that a) walls multiply the strength of defenders, so only useful if there's a decent defence within and b) you have 60% cultural defence (walls provide 50%) meaning that your only benefit from them is the slower bombardment - and if your army isn't yet in place he's very unlikely to stop and bomb.
This (probably) makes the walls functionally useless, and definitely of less use then another defender.
