Gaspari did it first but I don’t think he’s that much better than Branch. If they were competing in the same age I think they’d have similar physiques. Branch has a better structure generally, he was just sort of a victim of the times .
If he was a contemporary of Gaspari and relied on AAS more than gh/insulin, as well as incorporating more machines and less “slag iron” I think he would have had a very nice physique throughout his career, like what we see him present as a teen
Conversely, If Gaspari came up in the shadow of Ronnie and been tossing weights around like a construction worker, and grew on an all-you-can-eat hormona buffet I think he would have looked worse than Branch.
