The only chance Deviljho has would be his Dragon Breath. Beyond that, speed is the only thing in which it has an edge of Akantor/Ukanlos. However, their speed is subject to debate too.

Assuming we go by an Ecology-style confrontation, I wouldn't know what to think. Akantor seems pretty agile when he jump into the Gravios.

Anyhow, Akantor/Ukanlos simple outclass Deviljho in any possible way but presumable speed.
