We are talking about War here right? not Savage Hulk, or Maestro. From all indications, War was able to do what Thor could not do, and that is physically stop Cain. War did better he actually stopped him dead and threw him away as if he was a paper weight.
Durability? Hulk was phased into the cement and was able to rip himself free, when this happened to Thor he was helpless. To say things like "If the Hulk did not have a healing factor he would have died long ago" is unfair, because the same could be said of Thor. If Thor did not possess Mjolnir people like Hercules, Juggernaut, classic Wonder Man and the likes would beat him senseless. Gladiator would kill Thor without the hammer, The Hulk on the other hand beat him with his bare hands on panel, and it is canon.
To compare War to Savage Hulk is a mistake. The writers at Marvel have already put that to rest years ago when Dale Keown sketched for the title. It was stated that Professor Hulk started out stronger than he was in the past. Bruce said that in his Savage days that he was an adolescent in power and that he has gotten more powerful. Opponent that gave him a fight in the past were also easily dispatched.
WWHulk shows another increase in his power levels. Larceny you should stop posting those old scans of the test of strength between Bruce and Thor, because they no longer apply. War was amped to unimaginable levels via Celestial tech. Classic Thor would likely be pulverized if he mixed it up with him, Just like Cain was. Just remember Thor has never gotten the best of cain without magic, War did.
