Good Charge Balde for Fatalis with pre-Fatalis gear?

mhchargeblade.net suggets an anti-fatalis build with Safi bindshield with all attak V + VI awakenings.

Luckily, I have already one. Unfortunately I saw this build now that the safi siege isn’t active, so I didn’t have enough dracolite and ended up with like attack V x3, IV and III, even with all melding etc.

Would this weapon still be the best in slot or should I go for Alatreon/Lightbreak?

(I think I’d go for a savage axe playstyle, I personally found it really hard in solo to land an AED in Iceborne endgame without getting punished sadly.)
