Thunderstrike and Magni has the edge.
Current Juggernaut strenght fluctuates, and it's a mid-low level Class 100 most times.Every day he lose a part of his powers.
Magni on the other side, is even STRONGER than Classical Thor.He stayed fist to fist with DESAK, God Slayer and superb fighter, he was able to hurt him, and dropped on him a mountain sized building.
And he also has got Mjolnir.Thunderstrike has got less strenght and durability, but great experience in battle and also a copy of Mjolnir, the Asgardian guys have more tricks under their sleeves and they will do a perfect team work.Drax will go down considering Classical Thor stalemated him, Magni aided from T-Strike will K.O. him.
