Fight of Giantman:William Barrett Foster vs Henry Pym

These 2 were both Giantman.

So who would win if these 2 fought

And yes I know these to had contact to eachother.

Atlas from Thunderbolts would own them.At his max size, 60feet, he's over Class 100 and almost invulnerable.

Dr. pym.
I just think he'll win due to his ant powers.
