In G1, Megatron is equal to Optimus in a one on one fight. He beats Optimus a couple of times (once fatally). In Animated, Megatron was nearly scrapped by a bomb Starscream planted on him, and he was still almost too much for the Autobots. And shortly after he was rebuilt, he nearly wiped out the lot of them.

In the first episodes, Megatron seems to slow down Optimus pretty hard, but ultimately is overwhelmed by Optimus' overall strength, speed, and adaptability. In their final battle, Optimus pretty squarely wins, though Megatron had purposely de-gunned himself for the initial exchange.

On the battlefield, there are few who rival Optimus Prime's power. He is easily one of the strongest Autobots and his long range and melee weapons are as deadly as ever. He would sacrifice his life to protect his fellow Autobots or those under their care and does so on a regular basis.
