It has 1.5 times the explosion radius. The maximum damage potential (area * damage) for the obsidian coconade is slightly higher than 3 times the potential for the coconade. So from a math standpoint, 3 cocondes < 1 obsidian coconade. For a large group of enemies, obsidian version may have a practical advantage.

Still, I agree that it isn't worth it, but it isn't bad enough to ignore completely. It may be situationally useful.
