Strength: Dante has nothing on Ganon's raw strength.
Speed: Dante, easily.
Durability: Ganon, even if you take away his invulnerability, or maybe slightly Dante due to healing factor.
Power: Ganon by far, the guy is like one of the greatest magicians in gaming history, and has many feats to back that up.
Versatility: Maybe even.
Swordskill: ROFL Ganon. Come one dude.
Reach: Ganon.
Range: Meh, Dante, not by a whole lot tho, mostly just cause he has guns.
Experience: Ganon is far older, and has seen much more.
I am not a Dante expert, but that is my take. Also, I swear to God if anyone comes in here claiming Dante fights Multiverse destroying entities just cause he did in Nocturne, I will f*ckin FREAK OUT! The game was noncanon, deal with it.
