Was Augustus a good Emperor of Rome?
Yes. He had the longest reign of any emperor, and his rule began what is known as the Pax Romana, a period of over 200 years of internal peace and stability which in turn led to prosperity for the empire as a whole, and when there was no serious threat to the empire from external enemies. Augustus stabilized the borders of the empire, reformed the army and administration so that it became difficult for generals (even popular ones) to convince their legions to follow them in any attempt to overthrow the central government, and carried out on an ambitious building program in Rome; he also authorized construction of many new towns and cities throughout the empire, to ensure that provinces also benefited from his rule.
