Superman W/Sword of Superman vs King Thor

Who wins?

A: PC Superman W/ Sword vs RK Thor
B: Post Crisis Superman W/Sword vs King Thor

Superman with his Sword would be a match aginst RKT.
What chance does King Thor have?

I edited it, so I gave 2 options.

how powerful is the sword?

I'm not exactly sure, but it's a piece of time and space. Or something to that. Or a piece of creation.

that's kinda vague.
are there any feets?

so before the universe was born, a sword specified for superman was created....god....

anyway, although intriguing as a concept there are no measurable feats to use IMO
