The Green Goblin will have a major advantage in physical ability. With superhuman strength comes superhuman resistance to injury: weapons that would normally do severe physical damage to an average man (razor blades, bullets) can do either less or no damage to someone with super tough flesh, depending on how strong they are. I think the Green Goblin is weaker than spiderman yet stronger by far than any normal human athelete, which would necessitate more savage weaponry than the comic book Joker usually has at his disposal.

The only weapon I know of in the comics that could harm Green Goblin, apart from dynamite, is the Joker venom. Despite Green Goblin's resistance to Injury, the Joker venom (called in the Batman movie "Smilex) can be administered through gas, oral ingestion, or even by the claw scratch of a cat saturated with the stuff. However, it i not listed as among the weapons you give the Joker, making Green Goblin's job far, far easier...

Then there is the thug factor. I do not know about Green Goblin and any cronies he uses, but Joker's are often nothing more than clown-getup mobsters. The one exception is of course Harley Quinn, who is cute as a button, superhumanly strong herself (after some augmentation in the comics, can take down the strongest non-powered man with two punches or so), has two African Hyenas who are under her absolute control (are very strong anmals, capable of cracking elephant bones in their teeth), and a huge mallet, as well as a Boxing glove pistol. Combined with acrobatic skills already olympic level before her physical augmentations, she could turn the tide. But you have not added her here either, making Green Goblin's victory all but assured...

Joker's last chance will be based on the TAR-21, whether it is capable of penetrating Green Goblin's flesh (?) and giving a lethal blow (??). A good list of this weapon's stats here would be useful.

I vote Green Goblin!
