Why I DON'T think that THOTU Thanos was more powerful than the Living Tribunal
It has constantly been stated that the LT is the most powerful being that will ever be seen in Marvel, yet the LT was defeated by Thanos when he got The Heart of the Universe. I don't think that THOTU made Thanos more powerful than the LT, but rather put Thanos close to the LT in terms of power.
From that point, it becomes a matter of skill. The LT has NEVER had to actually fight a real battle before. He was so powerful, he didn't need to really fight. Thus, he lacks any sort of combat skills. Thanos, on the other hand, has waged many battles and stood toe to toe with the greatest combatant in the universe.
If you took Mike Tyson in his prime and put him in a street fight with Arnold Schwartznegger in his prime, who do you think would win? Tyson! Arnold may be bigger and stronger, but all he has is power - no experience having to use that power in a fight. Tyson has less power, but he knows how to use the power he has to get the most "bang for his buck."
If Thanos had really been at the Tribunal's level, he wouldn't have stopped with just that universe. He would have gone from reality to reality to he dominated the entire Marvel Multiverse.
