Thor vs Superman (see details )

Thor vs Superman (regular versions of both ) - Who Has Defeated More Powerful Enemies ?

Superman.

More, as in number of enemies? Superman (being in a comic 10x a week helps).
More powerful, as in power levels? Superman (5D imps being a regular part of his rogue's gallery helps).

I guess what I am trying to say, is Superman.

Regular unamped Thor has defeated

Galactus...Ego...Hela...Loki...Asgardian Destroyer...Savage Hulk...Silver Surfer...Midgard Serpent...Hyperion...Firelord...Gabriel ( robot )....Fin Fang Foom...Pluto...Perrikus...Desak...

This Thor has fought against

4th Celestial Host...Surtur...Mangod...Odin...Zues...Mephisto...Hercules...Seth...Immortus...Count Nefaria...Gladiator...Apocalypse

One of them has been around since the 20's and is in damn near every single DC comic

In a pure 1vs1 from start to finish, without any powerups?

Supes.
