I agree - I don't think there's a single part there that has been shared between the two figures.
I think the issue with the AoE figures is, like the first movie figures, they were taken from early concept drawings and produced in a shorter time frame, which meant the likeness was not as accurate and the engineering simpler.
By the second film, the designers knew which characters were being carried over and were able to spend longer time designing to the final character models, and we got the figures that we did.
