Pre-crisis Superman is faster than the Flash, stronger than the Hulk, can destroy a planet or a star with his HV, (has more destructive power than DBZ), has tanked the big bang, is immortal if he chooses to be, has moved at infinite speed, and lifted infinity...
HOWEVER....this battle is particularly difficult for him because of his WEAKNESSES.
His powers are vastly depleted by red sun radiation, and cosmic radiation is SS's forte, and his weakness to magic based attacks, and magic is Doctor Strange's forte.
Neither SS nor Strange can create Kryptonite, that would make this fight unfair.
Can Superman kill these two cosmic beings and top tiers before his powers are completely depleted? No sun-dip, that would make this unfair.
