Ap kogmaw vs Ap ziggs

In one combo? Over time? Be more specific.

Ziggs does more burst if everything lands (Center of his ult, every mine).

But kog has the longer range poke and can more easily clear a whole wave with just 1 E.

AP Kog is superior in every possible way. He has more range, and the hit box on his ult is probably larger than the one for Nidalee's spears, so it's easy to poke people.

Which champion does more ap damage

Neither - they're both tied at 0 AP damage.

RIP Veigar's AP stealing passive Entropy, he was the only champion capable of damaging AP :,(

you mean there is people playing ad ziggs?
