The Superhero Database Classification number, or SHDB Class, is a number that represents the overall 'power' of a character. All traits of a character are used for calculating the Classification.
What it DOESN'T mean
This doesn't mean that a higher class would always beat a lower class character. But the bigger the difference in Class is, the more obvious it is who'll win in a fight.
How is this calculated
( INT^1.3 + (STR*0.5 )^2 + (SPE*0.5)^2 + DUR^1.6 + (POW + (SPS*SPL))^2 + COM^1.8 ) ^ TIER
Super Power Score and Level
Every Super Power has a score (SPS) that is used to calculate the Class. Each Super Power also has 3 levels (SPL). The level is set when connecting that Super Power to a character. The level determines the final score, of the Super Power, being used in the calculation.
Speed: Attuma (this is close. Both have a very little amount of travel (land) speed feats. However Attuma is able to react to Okaye’s attacks which I consider a more impressive combat speed feat than Drax has ever presented.)
Power: Attuma (without Attumas vibranium blade I would give power to Drax for his overall physical presence, however vibranium weaponry combined with Attumas mastery of it makes him too powerful for even Drax)
Combat: Attuma (Attuma is much more skilled fighter than Drax. Drax heavily relies on his strength and aggression to defeat opponents)
Durability: Drax (both are bullet proof however, Drax has more feats and is not as affected by being in certain climates)
Strength: Drax (both around super soilder level, Drax’s visual feats on screen are more impressive)
Overall I think Attuma would have the advantage due to his superior fighting strategy/skill and his more advanced weaponary.
