This discussion about Anchor is quite valid. He possesses some cool special abilities, but his offensive spells weren't capable of dealing significant damage to Gray and Juvia. We know Gray wasn't at 100%—so he wasn't giving it his all—yet Anchor still struggled immensely when Juvia countered him.
And to end up exhausted from facing those two... honestly, I think Scissor Runner has an offensive spell with more raw power than anything Anchor demonstrated. The water dragon's best spell is his ability to reduce opponents into puddles of water, but that’s about it.
Motherglare is also a dragon that relies heavily on her physical attributes, as her magic lacks versatility. The debate between her and Levia is a valid one.
Among all the dragons, Levia possesses the best magic, given its great versatility. However, he falls short in terms of physical attributes—which are not nearly as impressive as Motherglare’s, let alone those of Earth Build.
Overall, Earth Build is the most well-rounded of the three, boasting insane physical attributes alongside versatile earth magic capable of handling offense, defense, and immobilization.
