Never noticed a stat boost for defenders.
Several problems though:
1. the attackers lose men to towers and other ranged units before they reach the top of the walls
2. the attackers lose men upon entering the walls because the defenders often strike before the attackers go into combat mode until the attackers have managed to spread out
3. the defenders will often surround the attackers from 2, maybe 3 sides(both sides of the wall and maybe cavalry on the street) resulting in a morale hit from being surrounded which can be quite severe
units which do not suffer too much from all these have a chance of taking a wall depending on who defends it, usually that is infantry with a onehanded weapon and a shield and good morale, positioning a general outside the wall to boost their morale can help but puts him in the range of enemy missile fire.
Trying to enter from multiple points with one or two units which only have enemies on one side of the wall, being the outer flank, can help as it allows one to surround the defenders and inflict a big morale hit on them as well.
