If Kaga had been completed as a battleship, she'd be stronger than Nagato. At least in terms of firepower (10 guns in five turrets. Some guns as Nagato). Akagi would have been similar but a battlecruiser...so less armor, longer with more horsepower and speed.

Given the way large carriers like Kaga made battleships utterly obsolete, it could be argued that she was anyway.

Just the tip of what?
