you're correct, its a moot comparison owing to the massive gap in technology. but if we control for inflation and for technology Rome is far more impressive.
we'd have to look at similar things for a valid comparison, the roman road system is far more impressive in both construction and upkeep than even the post-WW2 interstate highways of the US. They had better plumbing and waterway management than the modern US, etc. Again all controlling for inflation of technology.
i can 3d print a keychain today, 200 years ago a blacksmith may take a full day to make something similar. he's still far more impressive.
Rome and the U.S. have surprisingly similar histories. They were both basically backwaters until they started actively interferring with their neighbors to gain an economic advantage. In the case of Rome it was taking taxes, and the U.S. it was securing oil markets, but the point stands.
Similarly, Rome's fall came largely because of the transition from the masses owning land to becoming effectively serfs to the economically connected. Similar to what we are seeing now under neoliberalism.
Roman roads were impressive for the time, but so was the modern highway system. The reason Rome's roads lasted so long is because they didn't have semis driving down them.
I think the best measure might be Rome as a percentage of global GDP, versus the same measure for the U.S. There's no way to "adjust for inflation and technology" because modern economics didn't exist but for the past few hundred years, and the same for the massive boom in technology the past 100 years.
