HEYA!!!
The armies of Republican Rome were strongly rooted in the Italian peasantry. Rome's political reach was broader than comparable Greek states and military.
It's a common stereotype that Romans tended to be better at practical applications, while Greeks were more skilled at abstractions and theoretical pursuits.
Greece was a very contentious place; Rome on the other hand, maintained a far more continuous tradition of governance with far fewer interruptions.
Hope the answer has covered all your topics.
