The Sacred Beasts are pissants to the Egyptian Gods. Even their anime counterparts aren't nearly as good as the anime Gods. Horakhty is basically an infinitely powerful monster, while Armityle isn't really anything special beyond a giant beatstick. Horakhty has lore behind it, while Armityle was never given any special backstory or anything as far as I recall.
The only thing that comes close to Horakhty's power is Zorc, and we saw how that turned out. I was going to mention the Great Leviathan, but then I remembered it got beat by the individual Gods' combined attack.
