Magical Powers: Aku wins this one. His shapeshifting and overal magic is fare more powerful than Trigon's magic.

Physicality: Trigon wins this one. Aku spends most of his time as an entity without much real strength despite his powers.

Experiance: Aku wins. He was formed from a ball of pure evil and has had hundreds of years of experience between the timelines.

Burtality: Trigon wins due to his goal being to destroy, not take over the world.

Intelligence: Aku wins because Trigon does not have much tactics; however, Aku often uses his wits.

My vote goes to Aku. He can potentially outwit Trigon and has more magical power.
