Considering how DxD seems to follow the theme of Dragons being stronger than most races, I'm thinking that a low-class dragon would likely be able to handle most of the stronger members of other supernatural races.

If the Top 10 list didn't have certain individuals sharing a spot then Ddraig, Albion, Ophis and Great Red alone could have taken up nearly half the list by themselves before the former three's power loss.
