Gravios in general has higher health than Uragaan, although Uragaan beats it in speed, the Gravios would beat it in damage, such as its heat beam which is at best twice as strong as an Agnaktor's. Also, Gravios probably can handle the heat of the Volcano better than the Uragaan as in travels through lava so Gravios could use this as an advantage. Gravios has to face bigger threats such as Akantor as well, so it will have more battle experience, either way.
