Ph5 build, which is better?

Which layout is better? The other one more symmetrical while the other the mortars are separate. Any suggestions as well?

 

Personally I'd swap two canons from opposite corners with the bunkers and have the bunkers both face inward. In both designs an attacker coming from the ship side would be able to break through

 

How about this one?

 

Looks good, but you have enough walls to block in your mortar if you choose to do so

 

So its better that one of the mortar is on top and not next to each other? Also should i move the cannons on top next to the grog? I moved the 2 storages near pirate hall so i wont lose that much or should i move them inside the wall?
