Wudi was surpassed than Yuandi in term of troops, which had far more zeal and militancy than Yuandi.
Show me your source that Wu Di had more troops. And do show me how they are more efficient, as Han Shu once mentioned, Cheng Tang, the general who destroyed Zhi Zhi's empire in 36 b.c. once said that one Han soldier equal several barbarian (Wusun) troops.

Also please show me your source that the military strength, economic strength, and political influence of under Yuandi and Chengdi (as the fact the division of Xiongnu had nothing to do with them) was surpassed that of Wudi and Xuandi regin.
Read H. Dubb's economic journal on the Han to see for yourself on the economic comparison. The population under Wudi didn't surpass 40 million. While the census in 2 a.d. shows a population roughly 59,590,000 so yes its more in both population and GDP(but not in per capita).
Do I really need to explain political influence? You should know that yourself, during Yuan Di, Han's influence spread into the Aral sea, the Wusun, Kangu, Wu Huan, Xiong Nu all recognized Han supremacy, none of which recognized Wudi's supremacy. Wudi didn't even control the Tarim Basin yet. The protector general's status started in 60 b.c. and held an absolute control over the 50 states of the Tarim in which Wudi merely had Hami and Loulan and both of which are ready to switch allegience to xiongnu the instance they gain a victory. Under Yuan Di over a quarter of the world's population and resource lay in the hand of the celestial empire. Under Wudi only a sixth lay in the hand of Han.

There's no peak during Yuandi regin, Yuandi was often criticise as a curse of the declined 宣帝中兴 Xuandi regin.
you are talking internal politics, but on the world scale for the Han as a world power, Yuan Di's reign is the height of Han power.

Also, I didn't even mentioned anything about Zhenguan (Li Shimin), I had no idea why did you started out, the internal structure of Zhengguan was mess, there were plenty of enemies, the surrounded relationship was not yet built (even if it did, it had sooner destroyed), both military strength (territory stabilized) and economic strength of Zhengguan were not as good as Kaiyuan (well, sorry not Tiaobao) and Wu Zetian regime. Please awake.
No, there wasn't plenty of enemies, what the hell are you talking about? during Zheng Guan, Tang reigned supreme in all four directions it controlled the Tu Jue, Kitan, tarim and Tubo was a vassal. The empire streched all the way to Siberia in which the Tie Le tribes of Xue Yang Tuo, Bai Ku han, and Uighurs weer all under Tang protectorate, under Kai Yuan none of them was, Tu Jue was independent and raided occasionally, Tubo was extremely powerful and was a competitor to Tang in the west, the Turgis empire is constanly revolting and so were the Kitans and Xi, Silla and BoHai were also competely independent. On the world scale, During Zheng Guan and Gao Zong's reigns Tang was the only supreme power, it ruled a third of the world's population. Under Kai Yuan, Yarlung Tubo, and the Umayyad Caliph were both great powers, the Ummayad is even larger than the Tang although not as powerful. Kai Yuan is richer and superior internally if thats what you are talking about, but on the world scale Kai Yuan doesn't come even close to Zheng Guan. You think Zheng Guan is a mess? Did you forget about An Shi revolt? During Tien Bao, the emperor could barely control his army!
As for Wu Ze Tien's Sheng Shen Zhou Chao been superior to Zheng Guan's reign in power, wake up yourself, her army could barely coupe with the Kitan rebellion and the raid of the Khan Mocho of Tujue. There were a lot of rebellions, such as one in 684 when she took power. The zeal of her soldiers are poor. This is clearly mentioned by Li Zhen Kui general of the Korean campaign in one of his letters he claim that his soldiers are poor and all they wanted to do is go home. He asked a soldier why? The soldier answered during the time of Tai Zong, every soldier is rewarded and so they fought with zeal, yet by the fifth year (660a.d.) the soldiers are no longer paid and rewarded well or granted ranks so they had no zeal to fight. The Fu Bing system was cleary in decline by 660a.d. and it became so inefficient that in 737A.D. the emperor decreed an order to created a permanent professional army on the border this strengthened the army yet weakened central control.
