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.

Winner: Ghost Rider, 7-11, High Diff.
Much as I love the Surfer I have to give this one to the Rider. As SS is not a weapon forged in heaven there is really nothing he could do to harm Ghost Rider. Battlefield removal is not an option because GR can open dimensional portals to take him anywhere and escape from anything. Even a black hole could not hold him as his magical form and steed of choice seem to be unaffected by traditional physics.
Both can travel at multiple light speeds and both have undefined but near enough unlimited upper strength. And if silver surfer somehow stuns the host? Then the spirit of Zarathos is released and surfer is in more trouble than ever. Zarathos is untroubled by a conscience like a human, is utterly remorseless and can unleash the full power of his demonic might. And at some point the surfer will look in his eyes.
Over the years Silver Surfer has shown ample regret over his actions as Galactus herald. Were Ghost Rider to use his pennnace stare on him it is all over. If faced with the pain of the billions of innocence lives he has probably sacraficed to feed his master, surfer would either go mad, catatonic or he might even die. Whatever the result he would never recover. Silver Surfer is one of my all time favourite characters but Ghost Rider massively guilt stomps.
This is Silver Surfer Vs Johnny Blaze/spirit of vengeance GR. If it was Robbie Reyes Ghost Rider he doesn't have the pennnace stare so although his hellfire would hurt the surfer it would probably end up a draw. And Reyes GR is lame anyway.
That alone means Ghost Rider can kill the Silver Surfer with penance stare.
