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.
However vader's durability(star level)is far better then Superman's AP.
Also let's not forget vader's telekinetic strength that held back an ocean which is like trillion pounds or tons.
Also Vader does have the force on his side which is a power superman has no resistance to.
So in conclusion:
Superman:
+ faster in travel speed.
+ Physically stronger in terms of lifting strength.
- Less durable.
- Has no ways to counter the force.
- Far less experience and versatility.
Darth vader:
+ far better durability
+ much better versatility and combat skills
+ more powerful
- Physically inferior
I would say vader will emerge victorious from this encounter
A singularity for those who dont know in the context of physics and space-time, refers to a point where certain quantities become infinite. But as i said if superman was not inside the "black hole" (inside the singularity) he do not become star level, he do not have resisted to a infinite amount of gravity he was just far when it happened as the guy from quora has calculated.

In the film “Man of Steel”, Superman escapes the gravitational singularity created by the collision of the Phantom Drives, but he was not inside the black hole, he was far away as u guys can see..
