The plywood should not have failed regardless in this case but 1/2" CDX, 4-ply, wood is fine as long as it is clipped in and installed properly. Metal is certainly worth the premium over asphalt in this case if you value a permanent roof that adds value to your home.

Undoubtedly metal is more durable and energy-efficient than asphalt shingles. You should go for metal.
