GG Alergy...it was a hard-fought battle

tbh kefkas skin looks more like some sort of stone golem...
i think that allergy's has better colour, Kefka's skin has a more rough type of texture.
I'd say that allergy has hit the target with the colour

(pls no h8 m8 my opini0n)

Kefka's conveys the evilness of the character much better. Plus I love the glowiness.

I have no idea who Ultron is, but Allergy's is more appealing to me. My vote goes to him.

Allergy 4 shizzle

i Go With Kefka.

Kefka Has More Design

My beef with Kefka's is that the body shape is weird and the face doesn't look too much like Ultron, more like a generic dragon thing.

Though to be fair Allergy didn't do much better with the face

I never saw the movies, I only read the comic books. I recognize kefkas to look more like ultron from that.

Kefka's skin is merely more enjoyable, not too messy and confusing, the colours are also more satisfying. Take my vote good Kefka

Also I love how Kefka's is based on the Age of Ultron comic series while Allergy's is based on the Age of Ultron movie which has absolutely nothing do do with the aforementioned comic other than the name and the titular character

I vote Kefka

Allergy.

Although, both are fantastic.

While I like the colors on Allergy's skin a bit more, to be honest, it doesn't really look like Ultron.

The overall design and shading of Kefka's skin gets my vote.
Sorry Allergy.

I'm going with Kefka since I can tell it's ultron and recognize it as Ultron. While Allergy Man nailed the colors from the movie I guess, his could be any robot. If he slapped any other label on I wouldn't tell it's ultron.

Kefka's, His Ultron looks like a rotten one. The Body structure is more like Ultron's.

The other persons one doesn't but has correct color.

I would have to go with Kefka's.

Klefka's is nice, would be better if it was silver though.

Allergy's' face looks squished

Edit:

An elaboration

Ultron's face in the movie has the very distinct flat section where his nose and upper lip should be, it's a pretty iconic feature of his. The skin has a very smushed and "baby-like" short faced look. The colors are spot on though

Kefka's looks more like a dirt golem

i'm going with Kefka's because of the body design

They are both very good however despite Allergy's nicer colour palette, Kefka has what I9 see as a more correct general body design, true to Ultron
