they both look cool but lionheart looks cooler and is stronger. with a strength stat of 255 if you could break the damage limit it would do around 22500 damage. i figured that out by fighting an iron giant and eventually his defense got very high due to a protect spell. he was so well protected that each hit of lionheart only did about 7500. i did the maths and if he was an enemy with no protect and a low/medium defense sat instead of high, each of the hits would have done over 20000 Damage. in terms of sheer power theres no real competition.
