I'm gonna say the strongest digimon is belphemon rage mode. He is so strong that just by suffering Belphemon Rage Mode's roar, Ultimate Digimon and below will have their data disintegrated and will instantly die, and not even Mega Digimon can escape unharmed.

AND omnimon is mega level digimon so belphemon rage mode would kill omnimon 1 hit
