Ziggs or Viktor?

Is basically a better version of at this point?

I've just tried him and he seems to be a lot more dangerous.

Laning - They both move around and try to proc TLD combos. Ziggs' damage is a bit less reliable but he also has 3 damage spells to work with (Vik only has 2) and an automatically empowered auto to time trades with. Sure you can't just throw Ziggs' Qs at max range and spam it or you burn your mana but as a player, the aiming seems fairly similar.

Roaming- seems to have better roaming in mid game with . If you run in bot with Ghost, place and move Chaos Storm and Gravity Field to zone and blast the key targets... if its timed well... double kill. Ziggs doesn't have that kind of mid game roam power... however (the next point)

Tower Push and Waveclear- has way better tower push. While has traditionally been the god of wave clear, I find that isn't that much worse at it (between Q and E you have more than enough to push if the other guy leaves). You have a tower execute (so faster mid tower push to prevent roams).

Lane and Teamfight Safety- is WAY safer. You can use your W to escape and worse comes to worse, you can Ult yourself and probably get off SICK AOE blast even if you die. cannot get away... you can Gravity Field and Ult yourself though as a last resort. However, can generally position more aggressively because you know you can W away.

Lane Kill Pressure- Honestly, they both try to poke the other guy down and then go for the burst. However, I'll give a slight edge because Chaos Storm applies immediate damage (compared to a delay in Zigg's Ult) and it can chunk if the enemy can't dash away.

Late Game Utility and Damage- I feel this is where starts becoming better. He has WAY more range than to work with. Yes has higher damage numbers because of his passive and more 100-0 burst up close but I feel this is largely negated by ' overwhelmingly superior range (and spammability of Qs). While has higher numbers (and his Q Lich Bane DESTROYS), has high enough numbers at some point to nearly 100-0 squishies and I think ultimately that's what matters.

PS: 's laser is slightly easier to aim than Qs but at the same time, 's Qs are not as sluggish as abilities. ...

So what do you think?

Who is better?
