I wouldn't call kryptonians completely invulnerable, it's hard to tell how much higher their durability was to any of the guys on Thor's team, because there just weren't any weapons/beings on their level in their respective film.
It could be argued that Kurse and Malekith were actually stronger than the Kryptonians (i'm not saying they are but go with me) Obviously the Asgardians and the Elves had strength and equipment far above the soldiers on Earth in MoS, so you could see it as Kurse and Malekith's opponents were tougher than the fodder Faora and Zod were ripping through on earth, rather than assuming the Kryptonians are much more powerful just because they seemed more impressive.
The Kryptonians have the speed advantage for sure but it's hard to tell if Thor's team are that much lower on durability. Both teams showed crazy power in their films, I don't think this is easily won for either team.
How can you say that? Thor got throw into a montain and that hurted him bad, Superman went through worse when he fell trying to fly and didn't get a scratch.
Seriously, I can't believe someone can watch both films and believe the asgardians and elves had a chance against the kryptonians and a in straight fight.
Faora alone would probably kill all of Asgard plus the elves. The difference is brutal. Thor took a beating from Kurse and was all hurt, yet that was nothing compared to what Superman went through. Just the fall from his first flight attempt was more damaging then that.
Speed is another factor. The fight would probably go like this: (pretended the gif is where I tried to put it).
