I prefer Krypton’s. His skin has more of a rocky texture, his face shape doesn’t look as goofy and he’s got the chin spikes.

Honestly it's not a high bar to pass since smallville had a limited budget and batman v superman just looked like a random monster

Superman and Clark’s doomsday I would say, proportionally fits doomsday more

Looks good but it does look like it came out of the Resident Evil franchise.
