"Nope. DC wins in or out of the Marvel Universe. LT is guardian NOT master of the MU. The HOTU was more powerful than LT."
Uh, there's a bit of a technicality there. The HOTU is the source of Cellestial Power, and what the Cellestial's used to empower Akhenaton (don't ask why). TOAA is the Head Cellestial (if you are familiar with the "4 Hosts of the Cellestials" storyline). The HOTU is HIS power. That's why Thanos was able to mop everything, he literally had the power of God.
Now with that said, I'm kinda leaning more towards the DC team now and it's not based on firepower. The Preacher that merged with Genesis (the demon/angel hybrid) has the "Word of God" as his power. His power is that he can control anyone that listens to him. ANYONE. And considering that Tribunal is more powerful than anyone save God (TOAA), and The Preacher controls the "Word of God", he's what tips the scales in DC's favor. Without him, I'd take Tribunal over the other four. When it's all said and done, Lucifer and Michael are still just rogue Archangels, and Saint of Killers is a redneck Angel of Death. They don't have "Supreme Power", and it takes Supreme power to defeat/override Tribunal. I'd say the "Word of God" counts as a Supreme Power.
