But your example describes Sasaki, who is already stated to be vastly superior to F/SN Gil in terms of swordsmanship.
As for Final Fantasy's Gilgamesh, he has fought on par with multiple parties in the series' history. Gilgamesh's chief rival,
Bartz Klauser, can copy any weapon and attack after watching it for a short amount of time. Gilgamesh also crossed blades with
Squall Leonhart, who is infamous for being one of the few to be able to handle a gunblade, a weapon so notoriously difficult to handle that Squall is one of the only two people in the history of an academy of super soldiers with the most advanced technology and training in the world to be able to use one effectively. Gilgamesh is also considered to be worthy competitor to be pitted against
Serah Farro and
Noel Kreiss, who in turn fought against
Lightning, the chosen of the Goddess of Death. These latter three individuals are on par with
Caius Ballad, a swordsman who has traveled through numerous futures and has refined his combat technique for thousands of years out of a desire for revenge.
In addition, in the age department, Gilgamesh's age is literally immeasurable due to the time he spends flying through the Void across history, adding weapons, stories, and experience to his arsenal in each and every place he visits.
