No and yes

No because all Legend dragons have an equal basepower of 300.

Yes because mirror and wind dragons have an weaker moveset than an legendary dragon. Crystal seem to have exactly the same moveset. Legendary Spell (the strongest legend move) can only be learn by Legendary and Mirror Dragon.
