In terms of Rome itself i think he was disastrous. He led the republic into an Empire and ultimately that resulted in the failures and problems that crippled it and resulted in it not being around today. That being said he was truly an historically great leader of men that could inspire, rule, plot, and strategies as well as if not better, than anyone in history, and his accomplishments are so great that even with his notoriety I believe he is underappreciated.

He was also a good keeper who could play at a world level, but was ultimately nothing too special and not comparable to the greats of his era.
