Tang Xuan Zong also differs from the other two in that the begining of the collapse of Tang started right during his reign. Neither Han Xuan Di nor Qian Long faced decline in their reigns. In fact in Xuan Di's case, there was no decline even afterwards.
In the area of bilateral international relationship, the Tang also stands out in contrast with the Han and Qing and more in line with dynasties like the Ming in that the political power of the Tang was greater, exerting its maximum range in its early phase rather than its middle phase.
The reign of Tang Xuan Zong, as economically powerful as it was, was not the period of the height of Tang political power. This has largely to do with Tang's neibour developments. We see an international world order forged by the Tang in its early phase in what can be considered a unipolar structure. This changed to a multipolar international system with the rise of Tubo and the recreation of the Tujue empire during Wu Ze Tian's reign. Then during Xuan Zong's reign, it reverted back again to a Tang dominated system of a much more restricted unipolarity.
Xuan Zong's reign marked the Tang as a power of "first among equal" rather than the position as a power without equal which it held during Tai Zong and Gao Zong's reign.
This is similar to the Ming dynasty in which the early period under Yong Le was more powerful in its bilateral relationship with the Mongols and Central Asians. But it was during Ming Sheng Zong's time that Ming saw its greatest prosperity and economic power.
This might have to do with the similarity between the FuBing and the Wei Suo system of military establishment, in fact we see an astounding parity in the political development in the early-middle period of the Ming and the Tang.
The Western Han military system is very different from those of the later periods in that the army was conscription based, rendering the military efficiency of the army largely equal throughout its reign. Unlike the Fu Bing, the mercenaries, the Wei Suo, or the Bannerman, the Han miltitary system does not see as much a decline of its military quality from long periods of peace in which the professional armies rot away from inexperience.
Tang during Taizong was indeed an unmatched superpower. None of the Europeans or the Byzantium could match up to the economic and military success of Zhenguan. Military wise, only the Arabs (at that time under the 3rd or 4th capliphate) could rival it; however Tang should have been stronger.
By Xuan Zong, there were a lot of rivals. However, tang should have still been the best overall. Economically and culturally, it can't be matched. Military wise, tons of rivals. Xuan Zong defeated Khitans and Tibet. In the 720s, Eastern Turks were reborn and defeated Tang. Luckily for them, Eastern Turk destroyed itself. However, in teh 751, the Abbasid Caliphate defeated the Tang.
Ming had high points in economic and prosperity under Wanli not because of Wanli. Wanli himself is known as a lazy emperor. The only reason because Ming had a high point was because Zhang JuZheng as prime minister was controlling everything for the first 10 years.
