What level should I be to fight Gilgamesh in FF12?

As a player seeking to engage in battle with the formidable Gilgamesh in Final Fantasy XII, I'm curious about the recommended level of preparedness. Given the reputation of this formidable opponent, I'm wondering if there's a general consensus among players regarding the ideal level to face him. I understand that each player's journey and character development are unique, but I'm interested in hearing if there's a widely accepted starting point or range of levels that would provide a more balanced and enjoyable encounter. Additionally, I'm also curious if there are any specific strategies or character builds that players have found to be particularly effective against Gilgamesh.
